Answer:

A = 49 pi inches^2 or approximately 153.86 in^2

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

14 pi = 2 * pi *r

Divide each side by  2pi

14pi/2pi = 2 pi r / 2pi

7 = r

Now we want to find the area

A = pi r^2

A = pi (7)^2

A = 49pi

We can approximate pi by 3.14

A = 49 ( 3.14)

A =153.86 in^2
