Hi there! Answer: r = 9 feet
We can find the area of a circle by using the following formula:
Area = pi × radius^2
A = pi × r^2
In this particular question, we have the following data:
The area (A) is 254.34 square feet.
Pi equals 3.14
Now let's fill in the given formula.
Divide both sides by pi (in other words: divide by 3.14).
Now take the square root of both sides of the equation. We only need to find the positive solution of this equation, because a radius cannot be negative.
Therefore, the radius is 9 feet.
