Starting with the general form of the equation of a circle (assuming the Frisby is circular) of radius r and center at (h, k):

In the problem, the center is given as (-2, 1) and the radius is half the diameter so that's 12/2 = 6 inches. Make the appropriate substitutions into the equation:
Simplify.
