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
The length of the piece of ribbon in inches is closest to 2πr, where r is the radius of the drum.
Therefore, the length of the piece of ribbon in inches is closest to 2π(12.25) = 24.50π ≈ 76.95 inches.
