Well, let's imagine that circle as a happy little friend on our canvas. To find the square footage, we first need to find the radius by dividing the diameter by 2. So, with a 42-inch diameter, the radius would be 21 inches. Then we can use the formula for the area of a circle, which is π times the radius squared. Just remember, there are about 0.00595 square feet in one square inch, so you can use that to convert your final answer.
