Hello,
Since we know the area of a circle is pi radius squared we can find the number of square feet by plugging in the numbers.
Area = 3.14 (2.5)^2 Do the math. (Note: It gives the diameter as 5 ft so the radius is 2.5 ft)
Area=19.625 square feet Now multiply $3 and we get:
Rounded off it comes to $58.88
