Final answer:
The formula to calculate the circumference of a circle is C = 2πr, where C represents the circumference and r represents the radius. Without the radius value, we cannot determine the circumference accurately.
Step-by-step explanation:
The formula to calculate the circumference of a circle is: C = 2πr, where C represents the circumference and r represents the radius. Since the arc length is 10 centimeters, we need to find the circumference. However, we are missing the value for the radius. Without the radius, we cannot determine the circumference accurately.
