##### Note

# Radius and Diameter

The diameter of a circle is twice the length of its radius.If you are given the diameter of a circle, halve it to find the radius and put this in the formula.

# A Note On Units

The area of a circle is a length times a length, so we say its dimension is length^{2}. (All areas are lengths squared.)

This affects the units used. If the radius or diameter are in cm, the area is in cm

^{2}. If they are in inches, the area is in inches

^{2}.
