Question

Find the surface area of the cylinder .The surface area of the cylinder is _ cm2.(simplify your answer . Type an exact answer in terms of pie .)

Answer 1

The surface area of a cylinder is

`A=2\pi rh+2\pi(r)^2`

Replacing the given information, we have

`\begin{gathered} A=2\cdot\pi\cdot6\cdot7+2\cdot\pi(6)^2 \\ A=84\pi+72\pi \\ A=156\pi(cm)^2 \end{gathered}`

Hence, the surface area is 156pi square centimeters.
