the radius of the base of a cylinder is 39 in and it’s height is 33 in. find the surface area of the cylinder in terms of pi
The surface area of the cylinder, with a radius of 39 inches and a height of 33 inches, is calculated using the formula for the surface area of a cylinder. It amounts to a total of 7386pi square inches, separating the calculation into the lateral surface area and the area of the bases for clarity.
Explanation:The question is about finding the surface area of a cylinder where the radius of the base is 39 inches and its height is 33 inches, all in terms of pi. To find the surface area of a cylinder, we use the formula: 2(pi)(r)(height) + 2(pi)(r)^2. Substituting the given values, we have 2(pi)(39)(33) for the surface area of the sides, and 2(pi)(39)^2 for the two circular ends.
Therefore, the total surface area in terms of pi is: 2(pi)(39)(33) + 2(pi)(39)^2. This simplifies to: 2562pi + 4824pi, resulting in a total surface area of 7386pi square inches.
This approach easily demonstrates the process of calculating the surface area of a cylinder by focusing on its geometrical components: the lateral surface area and the area of the two circular bases.

Maria is enclosing a triangular pen with wire fencing. Two sides of the pen measure 14 ft and 8 ft in length. Which inequality describes the possible length.
A. 14> x > 8
B. 22>x> 6
C. 8< x < 14
D. 6 < x < 22
Answer:
D. 6 < x < 22
Step-by-step explanation:
For a triangle, the third side must be less than the sum of the other two sides and it must greater than the difference between the other two sides.
The possible length of the third side of the triangular pen, given the Triangle Inequality Theorem and two given side measures, is best described by the inequality D. 6 < x < 22.
Explanation:To find the possible length of the third side of a triangle, we use the Triangle Inequality Theorem. The theorem states that the length of any side of a triangle is less than the sum of the lengths of the other two sides and greater than the absolute difference of the lengths of the other two sides. Here, we have the lengths of two sides as 14 ft and 8 ft.
So the sum of these two sides is 14 + 8 = 22 ft. The difference is |14 - 8| = 6 ft. Therefore, the length of the third side 'x' can range between the sum and the difference of the other two sides. Hence, the correct answer is D. 6 < x < 22.

help here plz ! …..A taxi company charges a flat fee of $6.00, plus $1.10 per mile after the first 3 miles. Sarah’s taxi cab ride cost $22.50. How many total miles did Sarah travel?
Answer:
Step-by-step explanation:
$6+$1.10=$22.50
Add 1.10 to 6 ,15 times And you will get 22.50
Answer =15 miles
The question is asking how long was Sarah's taxi ride based on the taxi fare. This can be solved using algebra to set up an equation and solve for the total miles. The solution indicates that Sarah traveled a total of 18 miles.
Explanation:This question involves a concept in algebra known as linear equations, which are used to express variable relationships. Similar to the Svetlana's tutoring fee problem, this taxi fare problem can be solved by writing an equation based on the given information.
The equation would look like this: $6.00 + $1.10(miles - 3) = $22.50 where miles represent the total miles traveled by Sarah. Subtract $6.00 from both sides: $1.10(miles - 3) = $16.50. Divide both sides by $1.10 you get: miles - 3 = 15. Now, if we add 3 to both sides of the equation, we get: miles = 15 + 3 = 18.
So, Sarah traveled a total of 18 miles for her taxi ride.

A theme park has a ride that is located in a sphere. The ride goes around the widest circle of the sphere which has a circumference of 540.08 yd. What is the surface area of the sphere? Use 3.14 for pi.
Answer:
[tex]92893.76 \text{ Square Yards}[/tex]
Step-by-step explanation:
The widest circle of the sphere circumference of 540.08 yd.
Therefore:
[tex]\text{Circumference of the widest circle, } 2\pi r=540.08\\r=540.08 \div (2*3.14) =86 yd\\$Radius of the sphere =86 yd[/tex]
We proceed to calculate the Surface area of the sphere.

Which is an equation of the line containing the points (4, 10) and (6, 11) in standard form?
A. –x + 2y = 16
B. x + 2y = 24
C. x – 2y = –16
D. 2x – y = –2
Answer:
Option C, x - 2y = -16
Step-by-step explanation:
Step 1: Find the slope
[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]
[tex]m = (11 - 10) / (6 - 4)[/tex]
[tex]m = 1 / 2[/tex]
Step 2: Plug in into point-slope form
[tex](y - y_1) = m(x - x_1)[/tex]
[tex](y - 10) = 1/2(x - 4)[/tex]
[tex]y - 10 = 1/2x - 2[/tex]
Step 3: Solve for x
[tex]y - 10 + 2 = 1/2x - 2 + 2[/tex]
[tex](y - 8) * 2/1 = 1/2x * 2/1[/tex]
[tex]2y - 16 = x[/tex]
Step 3: Put the variables on one side

A store offers a 15% discount on a freezer chest that was originally priced at $630. If the sales tax rate is 7.8%, how much must you pay to buy the freezer chest?
Answer:
$577.27
Step-by-step explanation:
When offered 15% discount, buyer will then pay 100-15=85% of the original price hence the price offered by seller will be
0.85*$630=$535.5
Now this price is subjected to a tax of 7.8%, equivalent to 0.078 hence the buyer pays 1.078 of $535.5
1.078*$535.5=$577.269
Rounded off, this is equivalent to $577.27
