Question

The area of a circle is 3.14 square miles. What is the circles radius?

Answer 1

1 mile

Explanation:

Area of a circle is pi (3.14) times the radius squared

A=πr^{2}

Answer 2

Formula of the area of a circle is:

`a = 2\pi \: r`

So:

`3.14 = 2\pi \: r \\ \pi = 3.14 \: so \\ 1 = 2r \\ r = (1)/(2) = 0.5`

Answer: the Cirlcle's Radius= 0.5

Good luck.
