Question

The circumference of a pizza is approximately 44 inches. Estimate the area of the pizza.

A. 154 in2
B. 14 in2
C. 7 in2
D. 53 in2

Answer 1

The area of a circle equals to:
\[r ^{2}\times \pi \]

Answer 2

First you need to find the radius of the circle, given the circumference.
To do so, we know that 44=2*3.14*r
Divide 44/3.14=14.01
Divide 14.01/2=7
the radius is about 7in.

use the formula given to find the area of the circle.
\[7^{2} \times \pi\]
We know that 7 squared=49.
Then 49*3.14=153.86
153.86 rounds to 154in.

Answer should be A
