The perimeter of a circle is the circumference of the circle.

CIRCUMFERENCE

There are two formulas:

1. C = πd (use if the problem gives you the diameter only)

2. C = 2πr (use if the problem gives you the radius only)

AREA

There are several area formulas for a circle but I think for you at your level of math, A = πr^2 is all you need to know.
