Answer 1

11,300 ft.²

Explanation:

First you would need to use the pythagorean theorem (
`a^(2) + b^(2) = c^(2)`) to find the missing side of the triangle

`80^(2) + x^(2) = 100^(2)`

6400 +
`x^(2)` = 10,000

`x^(2)` = 3600

x = 60

Now that you know the missing side is 60, that side is also the radius, so you would plug that into the formula for the area of a circle (
`\pi r^(2)`)

`\pi`×
`60^(2)`

3600
`\pi`

≈11,309.73 so approx. 11,300 ft.²
