Question

Find the surface area of a cylinder with a base diameter of 4 ft and a height of 5 ft.

Write your answer in terms of π, and be sure to include the correct unit.

5ft
4ft

Answer 1

28π

Explanation:

A =2πrh+2π
`r^(2)`

r=
`(4)/(2)` ft = 2

h= 5ft

A = 2π (2* 5 )+ 2π(2*2)

A= 2π (10)+2π (4)

A= 20π + 8π

= 28π
