How To Find Radius From Diameter. Radius formula is simply derived by halving the diameter of the circle. We can also use three points on a circle (or two points if they are at opposite ends of a diameter) to find the center and radius.
R = d 2 this is the simplest formula you can use to get the radius. Find the diameter of the sector? Formula to calculate radius from diameter.

This is identical to the method used for calculating the radius of a circle from. Formula to calculate radius from diameter. If you know the circumference it is a bit harder, but not too bad:
The Circumference Can Be Given By, C=Π*2*R.
When the diameter is known, the formula is radius = diameter/ 2. The formula used to calculate circle diameter is: Just remember to divide the diameter by two to get the radius.
