The circumference of an 8 ft circle is: 25.1 feet.
diameter = circumference ÷ π = 10 ft ÷ π ≈ 3.18 ft
To calculate the area/circumference of a circle when designing something circular with a limited amount of material. i.e. you have to design a bronze circle and only have 27 sq ft of bronze. You have to calculate the circumference to see if you need to make the circle smaller or not.
If the diameter is 25 feet then the circumference is 78.5 feet (approx).
The formula to calculate the circumference of a circle is C = πd, where C is the circumference, π is pi (approximately 3.14159), and d is the diameter of the circle. In this case, the diameter is 35 feet, so the circumference would be C = π(35) = 110.19 feet.
