Answer:

2093pi/90 cm

Explanation:

You want the exact length of the arc subtended by a 182° central angle in a circle of radius 23 cm.

Arc length

The length of an arc of a circle is given by ...

s = rθ

where θ is the central angle in radians.

Application

The radian measure of an angle of 182° is ...

182°(π/180°) = 91π/90 . . . . radians

Then the arc length is ...

s = (23 cm)(91π/90) = 2093π/90 cm
