Answer:

153.86 square feet

Explanation:

The formula for the area of a circle is :
\pi *radius^2

To work this out you would simply multiply pi by the radius of 7 squared, this gives you 153.86. This is because if you were to substitute the values into the formula you would also get the same answer.

1) Multiply pi by 7 squared.


\pi *7^2=153.86 feet^2

In this question pi is as 3.14
