An arc is intercepted by a central angle of 3π2 radians on a circle with a radius of 18 centimeters. what is the exact length of the arc? enter your answer, in terms of π , in the box.

The length of the arc is

Step-by-step explanation:

step 1

Find the circumference

we know that

The length of a complete circle is equal to the circumference of the circle

The circumference is equal to

we have

substitute

step 2

we know that

A central angle of   radians subtends the circumference of

so

by proportion

Find the length of the arc by a central angle of radians

okay wait before i answer, is this for your points on a graph?

other answer is correct. i had used the radius of the radius somehow. a website:
