google circumference of a circle formula

anonymous · Answer

C=2πr

jabez177 · Answer

26 x pi x 2 = 163.28

jim_thompson5910 · Answer

that formula works if you use the radius

jabez177 · Answer

163.28 / 2 = 81.64

jabez177 · Answer

81.64 is my answer?

jim_thompson5910 · Answer

diameter = 26
radius = 13 (divide diameter by 2)

jim_thompson5910 · Answer

C = pi*d

or 

C = 2*pi*r


C = circumference of the circle
pi = 3.14 approximately
d = diameter
r = radius
