Question

32.What is the surface area of the cylinder?289 ft²17 ft17 ft

Answer 1

Given:

The cylinder with radius 17 ft. and height 17ft.

Required:

What is the surface are of cylinder?

Step-by-step explanation:

The formula to calculate surface area of cylinder:iven:

`\begin{gathered} SA=2\pi rh+2\pi r^2 \\ \text{ It can also be written as}: \\ SA=2\pi r(r+h) \\ Where, \\ r(Radius) \\ h(Height) \end{gathered}`

We have radius(r) = 17 ft. and height(h) = 17 ft.

`\begin{gathered} SA=2*\pi*17(17+17) \\ SA=34*\pi*34 \\ SA=1156\pi ft^2 \end{gathered}`

Answer:

Second option is correct.
