A circular drum has a radius of 12.25 inches. Karen wants to glue a ribbon around the edge of the drum. If Karen has exactly enough ribbon, which measurement is closest to the length of the piece of ribbon in inches? Responses A 38.465 inches38.465 inches B 24.50 inches24.50 inches C 76.93 inches76.93 inches D 36.74 inches
The length of the ribbon needed to go around the edge of a circular drum can be found using the formula for the circumference of a circle, which is 2πr, where r is the radius.
In this case, the radius is given as 12.25 inches. Plugging this value into the formula, we get:
Length = 2π(12.25) ≈ 76.93 inches
Therefore, the measurement closest to the length of the ribbon is 76.93 inches, which is response C.
