Question

What is the surface area of the cylinder? Use 3,14 for pi and round your answer to the nearest hundredth.

Answer 1

B. 226.08 sq in

Explanation:

Given data

r= 3 in

h= 9in

The expression for the surface area of a cylinder is

A=2πrh+2πr^2

Substitute

A= 2*3.142*3*9+ 2*3.142*3^2

A= 169.668+ 2*3.142*9

A= 169.668+ 56.556

A=226.224 sq in
