diameter = 10 cm
A. 15.7 cm
B. 314 cm
C. 78.5 cm
D. 31.4 cm

Answer 1

Answer:

C = 31.4 cm

Step-by-step explanation:

C = pi * d where d is the diameter

C = 3.14 * 10

C = 31.4 cm

Answer 2

Circumference = pi x diameter

                         = 3.14 x 10

                         = 31.4 cm

The answer is D. 31.4 cm.
