Given any 1 known variable of a circle, calculate the other 3 unknowns.

Radius of circle = r.

Webto find the area of a circle from the circumference, follow these steps:

Thus, the square inches of the circle is π × (1. 181 in)² = 4. 3825 in², which is 4. 3825 square inches.

A = πr 2.

The radius is the length from the center of a circle to the edge of the circle.

It doesn't matter whether you want to find the area of a circle using diameter or radius —.

The area of a circle is calculated by multiplying the radius r of the circle by π.
