Question

The circumference

of the circle shown above
is 108. The length of the minor arc AB is a pi. What is the value of a

Answer 1

Thus, the length of the arc AB will be 5/18 of the circumference of the circle, which equals 2πr, according to the formula for circumference. length of arc AB = (5/18)(2πr) = (5/18)(2π(18)) = 10π. Thus, the length of arc AB is 10π.
