Circumference = pi*40 feet
Chat with our AI personalities
The circumference of a circle can be found using the formula C = πd, where C is the circumference and d is the diameter. In this case, the diameter is 40 feet. So, the circumference would be C = π(40) = 40π feet, or approximately 125.66 feet.
circumference = diameter * pi. Therefore, diameter = circumference ÷ pi.
The circumference of a 12-foot-diameter circle is 37.7 feet.
Circumference of any circle = 2*pi*radius or diameter*pi
It is impossible to answer the question because the circumference cannot be 40 degrees.
