Question

Find the surface area of the cylinder round to the nearest tenth

What is the answer and how do I solve this?

Answer 1

62.8 cm is the answer to question

Answer 2

62.8 cm²

Explanation:

The formula for SA of a cylinder is:

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

with r being the radius and h being the height.

Let's substitute:

SA=2(2)(3)+22²

simplify

SA=26+24

SA=12+8

SA=20

SA=62.831

The surface area of this cylinder is 62.8 cm² (rounded to nearest tenth)

Hope this helps! :)
