Question

What is the surface area of this cylinder?

Use a ~ 3.14 and round your answer to the nearest hundredth.
7 ft
9 ft

Answer 1

`SA=703.36\ ft^2`

Explanation:

The picture of the question in the attached figure

we know that

The surface area of a cylinder is given by the formula

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

simplify

`SA=2\pi r(r+h)`

we have

`h=9\ ft\\r=7\ ft`

assume

`\pi=3.14`

substitute

`SA=2(3.14)(7)(7+9)=703.36\ ft^2`
