Question

What is the measure of the central angle of a circle with radius 18 centimeters that intercepts a12π centimeters arc?

Answer 1

Answer:
`120^(\circ)`

Explanation:

`12\pi=2(\pi)(18)\left((\theta)/(360) \right)\\\\12\pi =36\pi \left((\theta)/(360) \right)\\\\(1)/(3)=(\theta)/(360)\\\\\theta=120^(\circ)`
