First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.

About 153.86 square in. To find out the area of a circle do: r^2*pi.

im assuming your circle has a diameter of 1/4 inches to find sq in just find the area since the area is the definition of square inches. area = (3.14159) * (.252) = 0.196349375sq in

The radius of a circle is half of the diameter! So, if the diameter was four inches, the radius would be two inches!

Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter

Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
