Question

Find the surface area of a cylinder with a base radius of 4m and a height of 5m.

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

Answer 1

A≈226.19

Explanation:

The formula is A=2πrh+2πr²

you fill in the radius and get A=2π4h+2π4²

Then fill in the height and get A=2π4×5+2π4²

and your final answer would be A≈226.19
