Answer 1

Answer:

11,300 ft.²

Step-by-step 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
