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.

The first step in solving for the radius is to divide both sides of the equation by π to isolate the r^2 term. This gives you r^2 = 45/π.

The second step in solving for the radius would be to take the square root of both sides of the equation r^2 = 45/π to find the value of the radius, r. So, the equation becomes r = sqrt(45/π), which simplifies to approximately r ≈ 3.79 feet.
