5. Calculator Use. Use this circle calculator to find the area, circumference, radius or diameter of a circle. Given any one variable A, C, r or d of a circle you can calculate the other three unknowns. Units: Note that units of length are shown for convenience. They do not affect the calculations   Circle Circumference Calculator; Radius Calculator. What is a Circle's Area? The area of a circle is the space that is enclosed within its boundaries, as defined above. If you drew a perfect circle using a marker, then switched colors and filled in the circle completely - the color you switched to would be the circle's area.. To calculate the radius of a circle by using the circumference, take the circumference of the circle and divide it by 2 times π. For a circle with a circumference of 15, you would divide 15 by 2 times 3.14 and round the decimal point to your answer of approximately 2.39. Be sure to include the units in your answer It can be also used to calculate other parameters of a circle such as diameter, radius and area.
