The circumference of a circle. This is the total amount of length around the circle.
C= Circumference
R= radius of the circle

C = pi*r82 C = Pi*r*2 90=R Thus 180*Pi
C = pi times 2 radius or radius = C / (pi times 2) = 96.5 / (3.14 times 2) = 96.5 / 6.28 = 15.37
The circumference of a circle is: 2*pi*radius
C=2 pi r C = 2 * 3.14 * 3.5 cm C= 21.98 cm
Circumference is 2 times pi times radius, so the circumference of this circle is 2 times pi times 5, or 10 times pi. If a decimal answer is needed, pi is approximately 3.14, so C=31.4
