Question

The area of a circular pizza is 2122.64 square centimeters. What is the diameter of the pizza?

Answer 1

Area of a circle = pi x r^2

---For the purposes of this problem, pi = 3.14

2122.64 = (3.14)(r^2)

676 = r^2

r = 26 cm

Diameter = 2 x radius

diameter = 2 x 26

diameter = 54 cm

Answer: diameter = 54 cm

Hope this helps!
