Question

The distants around the edge of the pool is 38 feet. What is the area the pool with cover

Answer 1

`114.93 ft`

Explanation:

`\pi  = 3.14`

Given formula to find the area:

`\pi  * r^2`

Find radius first:

`Circumference = \pi  * 2 * r`

The circumference in this situation would be 38 feet.

`38ft = \pi  * 2 * r`

`38 ft = 3.14 * 2 * r`

`3.14 * 2 = 6.28`

`38ft = 6.28 * r`

Since we need to find radius, do division to 38 by 6.28.

`38ft / 6.28 = 6.05`

Our radius is 6.05

Now back to the original formula which is:

`\pi  * r^2`

Substitute:

`A = 3.14 * 6.05^2`

`6.05^2 = 36.6`

`A = 3.14 * 36.6`

`==> 114.93ft`
