Question

What is the surface area of a cylinder that is 30 feet tall and has a diameter of 52 feet?

Use 3.14 for π

______ ft.3

Round to the nearest whole number.

Answer 1

≈ 9144 ft^2

Explanation:

Given:

H = 30 ft

d = 52 ft

π = 3,14

Find: A (surface) - ?

First, let's find the radius:

r = 0,5 × d

r = 0,5 × 52 = 26 ft

Now, we can find the surface area of the cylinder ( the cylinder's surface area contains 2 circle bases and a lateral surface):

`a(surface) = 2\pi {r}^(2) + 2\pi * r * h`

`a(surface) = 2 * 3.14 * {26}^(2) + 2 * 3.14 * 26 * 30 ≈9144 \: {ft}^(2)`
