The formula to calculate the area of a circle is A = πr^2, where A is the area and r is the radius.
Given that the area is 45 square feet, we can rearrange the formula to solve for the radius:
45 = πr^2
r^2 = 45 / π
r = √(45 / π)
r ≈ √(14.25)
r ≈ 3.78 feet
Therefore, the approximate radius of a circle with an area of 45 square feet is 3.78 feet.
