The formula for finding the radius of a circle is circumference divided by double of pi. If area is given instead of circumference, the radius may be found by dividing the area by pi, then finding the square root of the resultant quotient. It is also equal to half of the diameter, or the diameter divided by 2.

The formula for the volume of a sphere?
2 pi r times the circumference sqaured. then take this and find out its square root. This however, only works if you have the circumference. If you have both the volume and the height, you can find the formula for the radius by solving the following literal equation for "r": V=1/3 r^2(3.14)(H) r=(3V/pi H)square root
