The circumference of a circle is 22pi inches. Find the area of that circle. Substitute 3.14 for pi. Express your answer to the hundredths place.

Answer 1

First, we need to find the radius of the circle using the formula for circumference:

C = 2*pi*r
22pi = 2*3.14*r
22 = 6.28*r
r = 22/6.28
r = 3.50 inches

Now, we can find the area of the circle using the formula:

A = pi*r^2
A = 3.14 * (3.50)^2
A = 3.14 * 12.25
A = 38.41 square inches

Therefore, the area of the circle is 38.41 square inches.
