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. This would give us r = √(A/π).
Step 3: The second step would be to plug in the given area of 45 square feet into the formula. r = √(45/π).
Step 4: The approximate radius would be about 3 feet.

is that the correct answer?
I apologize for the mistake in my response. Let me correct it.
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. This would give us r = √(A/π).
Step 3: The second step would be to plug in the given area of 45 square feet into the formula. r = √(45/π).
Step 4: Calculating the approximate value for the radius using a value of π ≈ 3.14, we get r ≈ √(45/3.14) ≈ √14.33 ≈ 3.78 feet.
Therefore, a good estimation for the radius of the circle with an area of approximately 45 square feet would be about 3.78 feet. Thank you for pointing out the error, and I hope this revised answer is helpful.
