The circle of a drum has the radius of 12.25 in 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
38.465 in
24.50 in
76.93 in
36.74 in
The length of the ribbon can be found by calculating the circumference of the circle. The formula to find the circumference of a circle is 2πr, where r is the radius of the circle.
Given that the radius of the drum is 12.25 in, we can calculate the length of the ribbon as follows:
Circumference = 2πr
= 2 × 3.14159 × 12.25
= 2 × 3.14159 × 12.25
= 76.94235
Rounding this to the nearest hundredth, the closest measurement to the length of the ribbon is 76.93 in.
Therefore, the correct answer is 76.93 in.
