the area of a circle is 2826 square inches. what is the length of its radius?

Area of a circle = Pi (3.14) * Radius^2.

Use this formula, and now plug in the numbers.

2,826 = 3.14*r^2.

Divide both sides by pi (3.14).

After doing so, you have this:

900 = r^2

In order to find r, you need to find the square root of 900.

√900 = 30.

The radius is equal to 30 inches.
