Find the volume of a right circular cone that has a height of 9.1 m and a base with a circumference of 12.1 m. Round your answer to the nearest tenth of a cubic meter.
Answer:
[tex]V=35.3\ m^3[/tex]
Step-by-step explanation:
-Given the cone's height is 9.1m and the Circumference is 12.1
#We use the circumference formula to calculate the radius:
[tex]C=2\pi r\\\\12.1=2\pi r\\\\r=\frac{12.1}{2\pi}=\frac{6.05}{\pi}\ cm[/tex]
-The volume of the cone using the radius above can then be calculated as follows:
[tex]V=\pi r^2\frac{h}{3}\\\\=\pi\times(\frac{6.05}{\pi})^2\times \frac{9.1}{3}\\\\\\=35.3\ m^3[/tex]
Hence, the cone's volume is [tex]35.3\ m^3[/tex]
Which line segment is a diameter of circle F?
Answer:
AC
Step-by-step explanation:
We know that a diameter of a circle is any straight line segment that passes through the center of the circle such that whose endpoints lie on the circle. It is also be known as the longest chord of the circle.
In the given figure we can see that only AC and BE are the line segments that pass through the center of the circle such that whose endpoints lie on the circle.
Answer:

factor completely 36x2 – 1.
Answer:
(6x - 1)(6x + 1)
Step-by-step explanation:
36x² - 1 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Thus
36x² - 1
= (6x)² - 1²
= (6x - 1)(6x + 1)

Solve the equation for x.
x/3 = (2x + 3)/7
Answer:
Our answer is [tex]x=9[/tex]
Step-by-step explanation:
First we will rearrange so we have to divide by 7.
[tex]\frac{x}{3}= \frac{2x+3}{7}[/tex]
Now we will cross multiply.
So...
[tex]x*7 \\3*2x+3[/tex]
Our new equation will look like:
[tex]7x=6x+9[/tex]
Now we have to isolate x.
So we have to subtract 6x from both sides.
[tex]7x-6=1x[/tex]
and
[tex]6x-6x=0[/tex]
Our new equation is:
[tex]1x=9[/tex]
Now divide.
Our answer is [tex]x=9[/tex]

What is the f?
f/5 - (-13) = 12
Step-by-step explanation:
[tex] \frac{f}{5} - ( - 13) = 12[/tex]
[tex] \frac{f}{5} + 13 = 12[/tex]
[tex] \frac{f}{5} = 12 - 13[/tex]
[tex] \frac{f}{5} = - 1 [/tex]
Now cross multiply
Therefore f = -5
Answer:
f= -5
Step-by-step explanation:
f/5-(-13)=12
remove the parenthesis and replace the negative with a positive.
f/5+13=12
multiply all by 5
f+65=60
move constant to the right
f=60-65
subtract 60 to 65

f= -5

What is the length of the diagonal of a 10 cm by 15 cm rectangle?
Answer:
18.02 cm
Step-by-step explanation:
A diagonal makes a rectangle into two right triangles. So if we use the Pythagorean theorem we can find the hypotenuse which is the diagonals.
Remember, because we know the length and width, we know the two sides.
10^2 + 15^2 = c^2
100+225 = c^2
325 = c^2
18.027 ≈ c
We can use the Pythagorean theorem to solve for the diagonal. The diagonal is the same as the hypotenuse of a triangle.
Pythagorean Theorem: a² + b² = c²
Now, solve for the diagonal.
(10)² + (15)² = c²
100 + 225 = c²
325 = c²
√325 = √c²
18.0277... = c
Round if necessary.
18.0277... = 18.03
Therefore, the diagonal of the rectangle is approximately 18.03cm.
Best of Luck!

Mrs. Hanson bought 1.6 pounds of grapes. The grapes cost $2.50 per pound. How much did
she pay for the grapes?
Answer:
$4.00
Step-by-step explanation:
Multiply the 1.6 pounds of grapes by the $2.50 per pound.
Answer:
4$
Step-by-step explanation:
Multiply 2.50$ with 1.6 pounds.
You get 4$
It won't cost more than 5$ because there are less than 2 pounds of grapes.
A 12-sided die is rolled. The set of equally likely outcomes is {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}. Find the probability of rolling a 9.
Answer:
1/12
Step-by-step explanation:
Since all are equally likely, each outcome has a probability of 1/12.
P(9) = 1/12
Answer:
1/12
Step-by-step explanation:
The probability of rolling a nine is given by the number of good outcomes over the total outcomes
P(9) = number of 9's / total
=1/12

An object is launched at 29.4 meters per
second (m/s) from a 34.3-meter tall
platform. The equation for the object's
height s at time x seconds after launch is
f(x) = -4.9x2 + 29.4x+ 34.3, where y is in
meters. What is the initial height of the
object?
29.4 meters
78.4 meters
34.3 meters
3 meters
Answer:
34.3 meters
Step-by-step explanation:
The generic equation for a movement with constant acceleration is:
S = So + Vo*t + (a*t^2)/2
Where S is the final position, So is the inicial position, Vo is the inicial speed, a is the acceleration and t is the time.
If we compare with our equation (where x is the time and f(x) is the final distance), we have that:
So = 34.3
Vo = 29.4
a = -9.8
So we have that the inicial position (So) of the object is 34.3 meters

Evaluate the geometric series. Please help me!!
Answer:
- 85
Step-by-step explanation:
The n th term of a geometric series is
[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]
where a is the first term and r the common ratio
1[tex](-2)^{n-1}[/tex] ← is the n th term of a geometric series
with a = 1 and r = - 2
The sum to n terms of a geometric series is
[tex]S_{n}[/tex] = [tex]\frac{a(r^{n}-1) }{r-1}[/tex]
= [tex]\frac{1((-2)^{8}-1 }{-2-1}[/tex]

The coordinates of point A on a grid are (2, -5). Point A is reflected across the x-axis to obtain point B. The coordinates of point B are (2, ___). (1 point)
Answer:
(2,5)
Step-by-step explanation:
If you are flipping a point over the x-axis, multiply the y coordinate by -1, if you are flipping something over the y-axis, multiply the x coordinate by -1.
The coordinates of point B are (2,5)
How does reflection across axis work?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If you study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
Given that coordinates of point A on a grid are (2, -5). Point A is reflected across the x-axis to obtain point B.
Since flipping a point over the x-axis, then we have to multiply the y coordinate by -1,
And ifyou are flipping something over the y-axis, then we have to multiply the x coordinate by -1.
Therefore, the point B are (2, _5_).

Jane is training for a triathlon. After swimming a few laps, she leaves the health club and bikes 24 miles south. She then runs 10 miles west. Her trainer bikes from the health club to meet jane at the end of her run. How much farther does jane travel than her trainer?
Answer:
26 miles farther from her trainer
Step-by-step explanation:
She starts her journey at health club,
Ran 24 miles south and then 10 miles west.
The distance between her end point and her trainer who was at health club can be calculated using pythagorean theorem.
X² = y² + z²
X = her end point
Z = distance between health club 24 miles south. = 24miles
Y = 10 miles distance from the 24 miles south. = 10 miles.
(See attachment for better illustration.)
X² = 24² + 10²
X² = 576 + 100
X² = 676
X = √(676)
X = 26 miles
Jane was 26 miles farther from her trainer
