Which of the following is the surface area of the right cylinder below?

height 2

radius 9

A. 174 units2

B. 187 units2

C. 198 units2

D. 162 units2

The lateral area of a cylinder (i. e. without the bottom and top lids) is 2πrh = 2π (9) (2) = 36π

The area of the two lids is 2[π (r^2) ] = 162π

The sum is: 36π + 162π = 198π

I guess the answers included π but you couldn't type it.
