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.
A 48-inch diameter circle has an area of: 12.57 square feet.
60 inch diameter = 2.5 ft radius.Area = pi*r2= 19.6 sq feet.
Yes, the circle's diameter is not bigger than the square base length.

60 inch diameter = 2.5 ft radius.Area = pi*r2= 19.6 sq feet.
Area of circle: pi*2.75 squared = 23.758 square feet to three decimal places
There are 100*pi square inches in a 20 inch diameter circle
Area of circle: pi*(20/12)^2 = 8.727 square feet rounded to 3 decimal places
