Answer 1

Hi there!
Seems like you are missing information of your question. Can you please add it?
We need:
-Circumference of the circle

Answer 2

If C is the circumference, 2piR=C. Therefore C/2pi = radius. Radius squared times pi = area. ((c/2pi)^2)*pi=area.

In plain English: The circumference is equal to two times pi times radius. The area is equal to pi times radius squared. Manipulating the formula for circumference you get C divided by two pi for radius. Squaring that result and multiplying it by pi gives you the area.
