Answer 2

The area left is equal to about 2686
`ft^(2)` (if we will round to the nearest whole number).

Explanation:

The area of the backyard that will be left will equal to the area of his backyard minus the area of the circular pool. So we can write it as...

The area left = (area of the backyard) - (area of the pool)

The area left =
`60 * 50 - \pi (20 / 2)^(2)`

The area left =
`3000 - 100\pi`

The area left ≅ 2686
`ft^(2)`
