Question

What is the surface area of the cylinder with height 8 in and radius 7 in? Round your answer to the nearest thousandth.

Answer 1

The formula to calculate the surface area of a cylinder is:

SA = 2πrh + 2πr^2

Given:
- Height (h) = 8 in
- Radius (r) = 7 in

Substitute the values into the formula:

SA = 2π(7)(8) + 2π(7)^2
SA = 112π + 98π
SA = 210π

Now, calculate the surface area:

SA ≈ 210 * 3.14159
SA ≈ 659.583

Therefore, the surface area of the cylinder with height 8 in and radius 7 in is approximately 659.583 square inches.

Answer 2

What is the surface area of the cylinder with height 3 m and radius 6 m

Answer 3

The formula to calculate the surface area of a cylinder is:

SA = 2πrh + 2πr^2

Given:
- Height (h) = 3 m
- Radius (r) = 6 m

Substitute the values into the formula:

SA = 2π(6)(3) + 2π(6)^2
SA = 36π + 72π
SA = 108π

Now, calculate the surface area:

SA = 108 * 3.14159
SA = 339.758

Therefore, the surface area of the cylinder with height 3 m and radius 6 m is approximately 339.758 square meters.

Answer 4

What is the surface area of the cylinder with height 8 ft and radius 3 ft

Answer 5

To find the surface area of a cylinder, you can use the formula:

SA = 2πrh + 2πr^2

Given:
- Height (h) = 8 ft
- Radius (r) = 3 ft

Substitute the values into the formula:

SA = 2π(3)(8) + 2π(3)^2
SA = 48π + 18π
SA = 66π

Now, calculate the surface area:

SA ≈ 66 * 3.14159
SA ≈ 207.35

Therefore, the surface area of the cylinder with height 8 ft and radius 3 ft is approximately 207.35 square feet.
