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: r = √(A/π).
Step 3: The second step in solving for the radius would be to substitute the given area (45 square feet) into the formula: r = √(45/π) ≈ √(14.3) ≈ 3.8 feet.
Step 4: The approximate radius would be about 3.8 feet.
