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)

Question

Step 1: What is the formula for finding the area of a circle? _______

Step 2: What would be the first step in solving for the radius? _______

Step 3: What would be the second step in solving for the radius? _______

Step 4: The approximate radius would be about _______

Answer 1

Step 1: The formula for finding the area of a circle is A = πr².

Step 2: The first step in solving for the radius would be to rearrange the formula to solve for r. r = √(A/π).

Step 3: The second step in solving for the radius would be to substitute the given area (45 sq ft) into the formula. r = √(45/π)≈√(45/3.14)≈√(14.33)≈3.78 ft.

Step 4: The approximate radius would be about 3.78 feet.
