Question

Can someone please help me?

Answer 1

Area of circle = 12.56 units²

Explanation:

`circumference = 2\pi \: r \\ 12.56= 2 * 3.14 * r \\ 12.56 = 6.28 * r \\ r = (12.56)/(6.28) \\ r = 2 \\ \\ area \: of \: a \: circle = \pi \: {r}^(2) \\ area \: of \: a \: circle = 3.14 * 2 * 2 \\ area \: of \: a \: circle = 12.56 \: {units}^(2)`
