Hope it will help you..!!What is the surface area of a cylinder that is 5 centimeters high and has a diameter of 1.5 centimeters?
A. 7.5π cm^2
B. 8.625π cm^2
C. 10.5 π cm^2
D. 19.55π cm^2
The surface area of cylinder is 8.625[tex]\pi[/tex] [tex]cm^{2}[/tex], if the cylinder has 5 centimeters high and 1.5 cm of diameter.
Step-by-step explanation:
The given is,
Cylinder has a 5 centimeters height
Diameter of the cylinder is 1.5 centimeters
Step:1
Formula for the surface area of cylinder is,
[tex]A=2\pi r h + 2\pi r^{2}[/tex]......................................(1)
Where,
h - Height of cylinder
r - Radius of cylinder
From the values of h and r,
[tex]r=\frac{d}{2}[/tex]
= [tex]\frac{1.5}{2}[/tex]
r = 0.75 cm
From the formula,
= ( 2 × [tex]\pi[/tex] × 0.75 × 5 ) + ( 2 × [tex]\pi[/tex] × [tex]0.75^{2}[/tex] )
= ( 7.5 [tex]\pi[/tex] ) + ( 1.125 [tex]\pi[/tex] )
A = 8.625[tex]\pi[/tex] [tex]cm^{2}[/tex]
Result:
The surface area of cylinder is 8.625[tex]\pi[/tex] [tex]cm^{2}[/tex], if the cylinder has 5 centimeters high and 1.5 cm of diameter.
The surface area of a cylinder is 8.625π cm². Thus, the correct answer is B.
First, calculate the radius of the cylinder, which is half of the diameter:
r = 1.5 cm / 2
= 0.75 cm
Next, find the area of the two circular bases of the cylinder using the formula for the area of a circle, A = πr²:
Area of one base = π(0.75 cm)²
= 0.5625π cm²
Total area of the two bases = 2 × 0.5625π cm²
= 1.125π cm²
Then, calculate the lateral surface area using the formula for the circumference of a circle (C = 2πr) multiplied by the height (h):
Lateral surface area = 2π(0.75 cm)(5 cm)
= 7.5π cm²
Finally, add the areas of the two bases and the lateral surface area to find the total surface area:
Total surface area = 1.125π cm² + 7.5π cm²
= 8.625π cm²
The correct answer is B. 8.625π cm².

If there are 16 pounds in one ounce, and you have 96 ounces then you must divide 96 by 16. That would mean there are 6 pounds in 96 ounces.
Step-by-step explanation:
So to answer the blocks you must divide the number of ounces by the unit rate. There are 16 ounces per pound.
What’s is the solution
4x-12y=-8
-3x+12y=12
The solution to the system of equations is x = 4 and y = 2.
Let's solve the system of equations:
4x - 12y = -8
-3x + 12y = 12
We can solve this system using the method of addition or elimination. Adding the two equations eliminates y:
(4x - 12y) + (-3x + 12y) = -8 + 12
Simplifying:
4x - 3x = 4
x = 4
Now that we have found x = 4, we can substitute this value back into one of the original equations to solve for y. Let's use the second equation:
-3x + 12y = 12
-3(4) + 12y = 12
-12 + 12y = 12
12y = 12 + 12
12y = 24
y = 24 / 12
y = 2

Step-by-step explanation:
There are two ways to find the value of m∠ ABT
By using trigonometric ratio:
1 - Draw a perpendicular AT
2 - Now the Δ ABT is a right-angle triangle. therefore by using trigonometric ratio
Sine X = Perpendicular / Hypotenuse
Sine X = AT/AB
X = Sine-1 AT/AB.
others ratio can also be used i.e cos x & tan x.
By using Circle Properties
1 - find the radius then the chord AB

can someone please solve this problem for me?
Answer:
5 and 7.
Step-by-step explanation:
Hey! So to start you need to create an algebraic expression. You can express this problem through the following equation:
*Note: if x is an odd integer, x + 2 is the next consecutive odd integer.
[tex]x *(x+2)=35[/tex]
Expanding, you get:
[tex]x^{2}+2x = 35.[/tex]
And moving the 35 to the other side, you get a simple quadratic.
[tex]x^{2}+2x -35 =0.[/tex]
Solving by factoring:
[tex](x+7)(x-5)[/tex]
This means two possible solutions for the smaller consecutive number are -7 and 5. However the question asks for two positive odd integers, so one of the numbers must be 5. The next will be 7(as its x + 2).

Answer:
C. 6 gallons < 25 quarts.
E. 80 pints = 40 quarts.
Step-by-step explanation:
A. There are 8 fluid oz in 1 cup.
Multiply 8 with 6:
6 cups x 8 = 48 fl oz.
44 fl oz < 48 fl oz ∴ A. is false.
B. There are ~6.67 pints in 1 gallon.
Multiply 6 gallon with 6.67:
6 gallon x 6.67 = ~40.02 pint.
47 pint > 40.02 pint ∴ B. is false.
C. There is 4 quarts in 1 gallon.
Multiply 6 gallons with 4:
6 gallon x 4 = 24 quarts.
24 quarts < 25 quarts ∴ C. is true.
D. There is 4 cups in 1 quarts.
Multiply 7 with 4 and add 4:
7 quarts x 4 = 28 + 4 = 32
32 cups < 34 cups ∴ D. is false.
E. 1 quart = 2 pint
You are given 80 pints:
80/2 = 40 quarts ∴ E. is true.

Which student wrote an equation that is equivalent to Mrs. McAlister’s?
Michele
Piotr
Ronnie
Tanisha
Answer:
Tanisha wrote an equation that is the same as Mrs. McAlister's equation.
9t = 8
Step-by-step explanation:
Mrs. McAlister wrote an equation on the board is:
10t-4t+3t=8
Now we simplify this
In order to simplify the left side, we combine like terms.
Here 10t, -4t, & 3t are like terms
So, 10t - 4t + 3t is equivalent to 9t
Thus,
9t = 8
This equation is written by the Tanisha.
That's the final answer.
I hope it helps you.
Answer:
Tanisha
Step-by-step explanation:
10t - 4t + 3t = 8 (given)
= 10t - 4t + 3t = 8
= 9t = 8
This is what Tanisha wrote (9t = 8)

The scale on a map is 1 cm = 30 km. The map distance between two towns is 3.5 cm.
What is the actual distance between the two towns?
Answer:
The actual distance between the two towns is 105 km
Step-by-step explanation:
Lets use a proportion for this scenario
1/30 = 3.5/?
We see that the numerator is multiplied by 3.5, from 1 to 3.5
So we do the same to the denominator
30 x 3.5 is 105 km
So your answer is 105 km
Answer:105 km

Change -25,49 to degrees, minutes and seconds
To convert -25.49 decimal degrees to degrees, minutes, and seconds, the answer is -25° 29' 24". This conversion involves separating the degree, multiplying the decimal part by 60 for minutes, and doing the process again for seconds.
Explanation:To change the decimal degree -25.49 to degrees, minutes, and seconds (DMS):
Use the absolute value of the decimal degree since the minutes and seconds are always positive. The integer part is the degree. So, here we have 25 degrees.Subtract the integer part from the absolute value of the decimal degree and multiply the result by 60. The integer part of this new number is the minutes. For -25.49, it's 0.49 x 60 = 29.4 minutes. So the minutes are 29.Again, subtract the integer part from the product obtained in the previous step and multiply by 60 to get the seconds. We take the 0.4 part from 29.4 and multiply by 60, which equals 24 seconds.The negative sign indicates the direction (west or south, depending on the context).
The answer is -25° 29' 24" (which might be west or south, depending on context).

What is the length of the Radius? Blank units
Answer:
12
Step-by-step explanation:
The measure of the radius of the circle C will be 12 units.
What is the arc length of the sector?Let r be the radius of the sector and θ be the angle subtends by the sector at the center. Then the arc length of the sector of the circle will be
Arc = (θ/2π) 2πr
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The central angle is 5π / 6 radian. And the arc length is 10π. Then the measure of the radius of the circle is given as,
10π = ((5π / 6)/2π) 2π r
Simplify the equation, then we have
5 = (5 / 12) r
r = 12 units
The measure of the radius of the circle C will be 12 units.
More about the arc length of the sector link is given below.

Plzz ANSWER FAST AS SOON AS POSSIBLE!!!
Answer:
See below for answers
Step-by-step explanation:
Part 1:
Angle 1 is a supplementary angle, so it must be 180-50=130 degrees because supplementary angles add up to 180 degrees.
Angle 2 is a vertical angle, therefore it must be 50 degrees as well because vertical angles are congruent.
Angle 3 is vertical to angle 1, so it is 130 degrees since vertical angles are congruent.
Part 2:
x and 2x+21 are supplementary angles, so we can make an equation:
x+2x+21=180
3x+21=180
3x=159
x=53
So x=53
Answer:
1 = 130
2 = 50
3 = 130
4 = x = 53
Step-by-step explanation:
angle 2 is congruent to 50 degrees
1 and 3 are congruent
1 and 2 are supplementary
3x+21 = 180
3x = 159
x = 53
