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: In this case, the area is given as 45 square feet, so the equation becomes 45 = πr^2.
Step 3: To solve for the radius, you would first divide both sides of the equation by π to isolate the r^2 term. This gives you r^2 = 45/π.
Step 4: The approximate radius would be about the square root of 45 divided by π, which is approximately 3.79 feet.
