The circumference is 56.52 , because you have the radius which is 9 but you need to find the diameter to do that you need to multiply 9 times 2 and it gives you 18 and then you just multiply it my pi and the value of pi is 3.14 and then the last step is it multiply 3.14 times 18 and it gives you 56.52
