Question

What is the surface area of the cylinder with height 4 mi and radius 3 mi? Round your answer to the nearest thousandth.

Answer 1

The surface area of the cylinder will be "131.88".

Explanation:

The given values are:

Height of cylinder,

h = 4 m

Radius of cylinder,

r = 3 m

As we know,

The surface are of cylinder is:

⇒
`A_s=2 \pi r(h+r)`

On substituting the values, we get

⇒
`=2* 3.14* 3(4+3)`

⇒
`=18.84* 7`

⇒
`=131.88`
