Question

The surface area of this cylinder to the nearest integer is

Answer 1

Option C.
`132\ in^(2)`

Explanation:

we know that

The surface area of cylinder is equal to

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

we have

`D=6\ in`

`r=6/2=3\ in`

`h=4\ in`

substitute

`SA=2\pi (3^(2)) +\pi (6*4)=42\pi\ in^(2)=132\ in^(2)`
