Question

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

Answer 1

The surface area of the cylinder is of 131.947 square meters.

Explanation:

Surface area of a cylinder:

The surface area of a cylinder of height h and radius r is given by the following equation:

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

What is the surface area of the cylinder with a height of 3 m and radius of 4 m?

`h = 3, r = 4`.

So

`S_a = 2\pi r(h+r) = 2\pi(3)(3+4) = 42\pi = 131.947`

Height and radius are in meters, so the surface area will be in square meters.

The surface area of the cylinder is of 131.947 square meters.
