Ther jester was juggling in the medieval fair, and all three where different sizes and colors. The jester wanted to put them in order from least to greatest. The red ball had a diameter of 100 mm the green ball had a radius of 4 cm and the yeallow ball had the radius of 6.5 cm. Find the circumference of each (be sure they are all in the same UNIT of measurment).

C = pi * d
Red:
C = 3.14 * 10 cm
C = 31.4 cm
Green:
C = 3.14 * 8
C = ?
Yellow:
C = 3.14 * 13
C = ?
