Answer: C = 56.52 cm

Explanation:

Our task is to find the circumference of the circle, given that:

  • the diameter is 18 cm

Applying the formula:


\sf{C=\pi * d} (C = circumference, d = diameter)

Plug in 18 for d, since it's the diameter; also, don't forget to use 3.14 for pi.


\sf{C=3.14*18}


\sf{C=56.52\:cm}
