Question

The circumference of a pizza is 75.36 in. What is the approximate area of the circle? Answers

A.(113.04 in2)
B.(37.68 in2)
C.(1808.64 in2)
D.(452.16 in2)

Answer 1

Circumference = diameter x pi

Find the diameter:

75.36 = diameter x pi

Divide both sides by pi:

Diameter = 75.36/3.14 = 24 inches.

Area = pi x r^2

R = 1/2 diameter = 12

Area = 3.14 x 12^2

Area = 452.16 in^2

The answer is D.
