AI explanation

Using the arc length formula l equals pi multiplied by r multiplied by theta divided by 180, we substitute the given values of 7 for r and 60 for theta. We get the fraction 22 over 7 multiplied by 7 multiplied by 60 divided by 180, which simplifies to 22 multiplied by 1 over 3. The result is 14.6 centimeters.
