What Is the Formula for Radius?

Answer

You can get the radius of a circle by dividing the diameter by two; thus radius = diameter/ 2. You can also get the radius of a circle by dividing the circumference by 2 multiplied by pi.
1 Additional Answer
The formula to find the radius of a circle is r=d/2. The letter 'd' stands for diameter, and 'r' stands for radius. In order to find the radius of a circle, you can just change the diameter formula of d=2r to find 'r'.
