A segment with endpoints C(-3, 3)and D(7, 3) is the diameter of a circle.

a. What is the center of the circle?
It's the midpoint.
----------------
b. What is the length of the radius?
1/2 the distance between the 2 points.
--------------
c. What is the circumference of the circle?
C+=+pi%2Ad+=+2pi%2Ar
-----------
d. What is the equation of the circle?
%28x-h%29%5E2+%2B+%28y-k%29%5E2+=+r%5E2 where (h,k) is the center.
