Feb 10, 2016 - The circumference, C, of a circle is found by the following equation: C = 2 x pi x r where r equals the radius of the circle (or half its diameter) and pi = 3.14159 (a constant). Thus, 6.28 = 2 x pi x r. Solving for r: 6.28/(2 x pi) = r. or: 6.28/(2 x 3.14) = 6.28/6.28 = r. thus r = 1 and since the diameter equals 2 x r, the ...
