How to Calculate Diameter?

To calculate diameter, you need to know either the radius of a circle or a formula that relates the diameter to another factor like circumference. For example, If you are given the radius, then twice the radius is you diameter. However, if you are given the circumference of a circle, you calculate the diameter by knowing that circumference C of a circle is equal to pi x (diameter). From this equation, you find that the diameter is equal to the C/pi. You can find more information here: http://www.mathgoodies.com/lessons/vol2/circumference.html
