If you have a circle with an area of approximately 45 square feet, what is a good estimation for the radius of the circle?(4 points)
A good estimation for the radius of the circle can be calculated using the formula for the area of a circle:
Area = πr²
Given that the area is approximately 45 square feet, we can rearrange the formula to solve for the radius:
r = √(Area / π)
r ≈ √(45 / 3.14)
r ≈ √14.3312
r ≈ 3.78 feet
Therefore, a good estimation for the radius of the circle is approximately 3.78 feet.
