+43 1. A pizza has a diameter of 16 inches. Which is closest to the area of one slice if the pizza is divided into 6 equal pieces.
2, What is the center and radius of the circle defined by the equation (x - 2)2 + (y + 3)2 = 30
+23246 The formula for the area of a circle is: A = pi·r2.
Since the pizza has a diameter of 16 inches, it has a radius of 8 inches.
Solve: pi·82 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 = r2 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).
