Assuming that you mean a 4ft wide circle then the area is calculated using A = Πr2
Π = 3.142, r = 2ft = 24in
A = 3.142 x 242in2
A = 1809.792in2

A circle with a radius of 24 inches will have an area of approximately 1809.56 square inches.
To find the circumference of a circle, you can use the formula C = 2πr, where C is the circumference, π is approximately 3.14159, and r is the radius of the circle. Since the diameter of the circle is 8 feet, the radius is half of the diameter, which is 4 feet. Plugging in the values, we get C = 2 x 3.14159 x 4 = 25.13272 feet. To convert this to inches, we multiply by 12 (since 1 foot = 12 inches), giving us approximately 301.59 inches around an 8-foot circle.
There are 12 inches in one foot. 48 inches are in 4 feet.
4 foot 5 inches = 135 cm.
