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)
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 _______
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.
