How To Calculate The Radius From The Circumference C = pi x d. You get the equation for circumference by solving for C in the equation above. C = pi x d. In addition, since you know that the diameter of the circle is twice as long as its radius, then: C = pi x 2r. Where, C = circle of the circumference. r = radius. Determine all … Volume of a Sphere Calculator - Kyle's Converter You can approximated PI using: 3.14159. If the number you are given for the radius does not have a lot of digits you may use a shorter approximation. If the radius you are given has a lot of digits then you may need to use a longer approximation. What are pi and radius - Answers Pi is constant and will always be 3.14.
