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 = πr^2, where A is the area and r is the radius.
Step 2: Since we are given the area as approximately 45 square feet, we can plug this value into the formula. 45 = πr^2
Step 3: To solve for the radius, we need to isolate r. Divide both sides of the equation by π: r^2 = 45/π. Then, take the square root of both sides to find r.
Step 4: The approximate radius of the circle would be about 3.0 feet.
