Walt, this is the solution:
First, let’s find the fraction of the circle’s circumference our arc length is.
65/360 = 13/72 = 0.1806
Second, we need to find the circumference, this way:
C = 2πr
C = 2π * 12
C = 24π
C = 75.3982 cm
Now, we can calculate the Arc length:
Arc length = 75.3982 * 0.1806
Arc length = 13.6 cm (Rounding to the next tenth)
