Question

Area of circle is 113.1 ft square. What is diameter?

Answer 1

`A = \pi {r}^(2) = \pi {( (d)/(2)) }^(2) =\pi \frac{ {d}^(2) }{4} \Rightarrow d = \sqrt{ (4A)/(\pi) } \\ \Leftrightarrow d = \sqrt{ (4 * 113.1)/(\pi) } = \sqrt{ (452.4)/(\pi) } \approx12 \: ft`

Answer 2

Bro the diameter is 12 ft.
