**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
