Question from Debra:

i have a radius of 73 inches, i need to know the length of the circle please.

Hi Debra.

Do you mean the distance around the outside curve of the circle? That is called the circumference.

If you know the radius, then you multiply the radius by 2, then by π (which is about 3.1416) to get the circumference.
