Area = pi*d = pi*20 = 62.83 sq feet (to 2 dp).
That's the circumference. Area is pi x radius squared = 100pi= 314.2 sqft approximately.

A circle with a diameter of 18 feet has a perimeter of 56.5 feet.
24' 6"
To find the circumference of a circle with an 8-foot diameter, you would use the formula C = πd, where C is the circumference, π is approximately 3.14, and d is the diameter. So, C = 3.14 x 8 = 25.12 feet. The circumference represents the linear distance around the circle, so in this case, there are 25.12 linear feet in an 8-foot diameter circle.
