How to find the Diameter of a circle
The diameter is the longest distance from one end of a circle
to the other; it is twice the radius.
The Diameter can be found by the following formulas
If you know the radius:
The diameter can be calculated using the formula.
Diameter = 2R or d = 2 x radius. R is for the radius of the circle.
Remember: The radius is half of the diameter of a circle
If you know the circumference of a circle, the diameter
can be found using the formula.
C is the circumference of the circle and π is Pi,
approximately 3.142
If you know the area, the diameter can be found using the
formula.
A is the area of the circle. And π is Pi, approximately 3.142
