Question

Find the surface area of this cylinder using pie.

Answer 1

Answer:

Thus the surface area of this cylinder involving pie is:

$A=750\pi$ ft²

or

$A\approx 2356.19$ ft²

Step-by-step 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

$\:A=\left(2\times \:\pi \:\times \:15\times 10\right)+\left(2\times \pi \:\times \:15^2\right)\:$

$A=750\pi$ ft²

Thus the surface area of this cylinder involving pie is:

$A=750\pi$ ft²

or

$A\approx 2356.19$ ft²
