ANSWER: 37.68
Why? Well this question is asking for the circumference...and you get the circumference by multiplying 3.14 (pi) by the diameter.
Final Notes: The formula for finding the circumference with the diameter is
(C =
d) (diameter times 3.14)
if you want the formula for finding the circumference with only the radius here you go, (Radius times 3.14 then times it by 2)
(C = 2
r)
Hope this helps!!
