Answer:

Approximately
153.94
in^2

Explanation:

Recall the formula for the area of a circle:


\pi r^2

Where r is the radius.

We are given that the radius is 7 inches. Let's plug that into our formula and solve it. We have:


\pi r^2=\\\pi (7)^2=\\\pi (49)=\\49\pi

From here, we multiply our answer by pi using a calculator and round.

  • Using a calculator, we can find that
    49\pi is approximately 153.93804 (round to the nearest hundredth: 153.94)
