The formula for the circumference of a circle is C = 2πr, where C is the circumference, π is approximately 3.14, and r is the radius.
Given that the circumference of the drum is 113.04 centimeters, we can plug in the values into the formula:
113.04 = 2 * 3.14 * r
113.04 = 6.28r
Now, we can solve for the radius (r):
r = 113.04 / 6.28
r ≈ 18.00
Therefore, the drum's radius is approximately 18 centimeters.
