The area of a circle is 1256 square inches. What is the radius?

The radius is 20.

Step-by-step explanation:

We know the area of a circle is found by

A = pi r^2

We know A = 1256 and pi is approximated by 3.14

1256 = 3.14 r^2

Divide each side by 3.14

1256/3.14 = 3.14/3.14 r^2

400 = r^2

Take the square root of each side

sqrt (400) = sqrt (r^2)

20 = r
