Answer: A, 6 cm
Step-by-step explanation:
Circumference is 2(radius) * pi.
A. 12pi C. 24pi B. 16pi D. 32pi
Assuming pi is roughly 3,
A = 36
C = 72
B = 48
D = 96
A is the closest and if you actually used pi, it would be about 3.14159265 which would make the circumference slightly over 36, which 37.68 is.
Hope this helped.
