For a button to fit through its buttonhole, the hole needs to be the size of the button's diameter. What size buttonhole is needed for a button with a circumference of 7.38 centimeters? (Use the value of 3.14 to represent pi, and the formula for circumference = 2*pi*r)
A button with a circumference of 7.38 cm will need a buttonhole with the size of 2.35 cm.
Since the circumference is equivalent to 7.38 cm, the formula can be displayed as follows: 7.38 cm = 2πr r = 7.38cm/2π r= 1.1751592 cm diameter = 2r = 2.3503184 cm or approximately 2.35 cm
