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

Answer:

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

Step-by-step 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

⇒       $=2\times 3.14\times 3(4+3)$

⇒       $=18.84\times 7$

⇒       $=131.88$
