If you have a circle with an area of approximately 45 square feet, what is a good estimation for the radius of the circle?
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 = πr^2 (where A is the area and r is the radius).
Step 2: The first step in solving for the radius would be to rearrange the formula to solve for r. So, r = √(A/π).
Step 3: The second step in solving for the radius would be to substitute the given area of 45 square feet into the formula. So, r = √(45/π) ≈ √(14.32) ≈ 3.78 feet.
Step 4: The approximate radius would be about 3.78 feet.
