Question

Find the surface area of this cylinder using pie.

Answer 1

Thus the surface area of this cylinder involving pie is:

`A=750\pi` ft²

or

`A\approx 2356.19` ft²

Explanation:

Given

radius = r = 10 ft

height = h = 15 ft

The surface area of a cylinder formula is:

`A=2\pi rh+2\pi r^2`

substituting the value = r = 10 ft and h = 15 ft

`\:A=\left(2* \:\pi \:* \:15* 10\right)+\left(2* \pi \:* \:15^2\right)\:`

`A=750\pi` ft²

Thus the surface area of this cylinder involving pie is:

`A=750\pi` ft²

or

`A\approx 2356.19` ft²
