The formula for the area of a circle is: A = pi·r^{2}.

Since the pizza has a diameter of 16 inches, it has a radius of 8 inches.

Solve: pi·8^{2} and divide this answer by 6 to find the area of one slice of the pizza.

A circle has: (x - h)^{2} + (y - k)^{2} = r^{2} for an equation, where the center is (h, k) and the radius is r.

In this problem, h = 2 and k = -3 and r = sqrt(30).
