for a button to fit through its buttonhole, the hole needs to be the size of the button diameter. What size buttonhole is needed for a button with a cIrcumference of 7.3 centimeters? Use the value of 3. 14 to represent pi



Answer :

If C is circumference, then C=2πr, where r is radius. Plug in 7.3 as C and solve for r. This leaves you with 3.65π. However, radius is only half of the diameter. To obtain the amount needed, one multiplies it by 2, which is 7.3π. That is your answer.
