Question

Find the surface area for a cylinder 12 in tall and has a diameter of 14

Answer 1

228π in²

Explanation:

The formula of a Surface Area of a cylinder:

`S.A.=2\pi r(r+H)`

r - radius

H - height

We have H = 12 in na diameter 2r = 14 in → r = 7 in.

Substitute:

`S.A.=2\pi(7)(7+12)=12\pi(19)=228\pi\ in^2`
