What is the equation of a circle with radius 4 and center (0,8)?

The equation of circle with the center at (h,k) is:

r stands for radius. Therefore r^2 = diameter or 2×radius.

The question has already given the information we need, which are:

Since the center is (h,k) - therefore the center is at h = 0 and k = 8 making it (h,k) = (0,8).

Substitute the values in the equation:

Simplify to the simplest form
