Answer:

See below.

Explanation:

The area of the circle is given by the formula:


A=\pi r^2

From the circle, we can see that the diameter is 14. Thus, the radius must be 14 divided by 2 or 7.

We're also using 3.14 for π. Substitute:


A=(3.14)(7)^2

Use a calculator:


A\approx153.86

And we're done!
