Include units in your answers. Example d = 10 cm C = 31.4 cm Think: C = π \times d = 3.14 \times 10 = 31.4 . If you are given the radius, double it first. 1 r = 6 mm Find the circumference. 2 d = 50 cm Find the circumference. 3 d = 36 m Find the circumference. 4 d = 14 mm Find the circumference. 5 d = 50 in Find the circumference. 6 r = 18 ft Find the circumference.
