C = π d
C = π x 8 ft
C = 25.1 ft (to 1 decimal place)

Circumference = pi * diameter
pi = 3.14159 26535 ...
8 * pi = 25.133 = 25 feet, 1 and 9/16 inch

circumference equals pi (3.141592653589793....) times the diameter. the circumference of a circle with a diameter of 8feet is pi x 8, or 25.132741 feet.

i believe the circumference of a circle is pi * d, or 3.14*diameter
dont believe the other dude its not pi * r squared, as that is the formula for area
