---------
C = 2pi*r
--> r = C/(2pi)
=====================
Area = pi*r^2

So
The area of the circle is equal to
Q: in China, spheres are used to exercise a person's hands. if the diameter of a sphere is 2 inches how many square inches are in its surface area express your answer in terms of pi.
sOLUTION: If diameter = 2 inches, then radius= (2 inches)/2 = 1 inch
The area of the circle is equal to
A = sq inch
You can put this solution on YOUR website! circumference of the circle:
pi*2r = C
Area:
pi*r^2
------------------------------
4*pi*r^2 area
4*pi*2^2 = area
4*4*pi = area
16pi = area
