If the arc length of a sector in the unit circle is 3π/2 , what is the measure of the angle of the sector? a) 0 radians b) π/2 radians c) π radians d) 3π/2 radians

D) radians

Step-by-step explanation:

In geometry, the radius of a unit circle = 1 unit.

Given: The arc length of a sector in the unit circle

We know that the formula to calculate length of arc having central angle x and radius r is given by  :-

Substitute r= 1  and   in the above formula , we get

Hence, the  measure of the angle of the sector radians
