Question

Mark placed a pool in his backyard, which is enclosed by a triangular fence. The radius of the pool is 20.5 feet How much of the backyard is not covered by the pool? Use

Answer 1

2644.415 feet spuared

Explanation:

I think the attached photo is your full question, and my answer:

We need to find:

- the area of the pool = π
`r^(2)` = 3.14*
`20.5^(2)` = 1319.585 feet spuared.

- The area of the triangular fence = 1/2* 84*92 = 3964 feet spuared

So, the area of the backyard which is not covered by the pool is:

The area of the triangular fence - the area of the pool

= 3964 - 1319.585

= 2644.415

Hope it will find you well.
