What is the measure of the indicated central angle?

A) 70 degrees

B) 80 degrees

C) 90 degrees

D) 110 degrees

E) None of the above

Answer 1

Answer:

Step-by-step explanation:

Given,

r=3

arc=3/2*pi

we know that,arc=theta(angle)*2*Pi*r/360

theta*2*pi*3/360=3*pi/2

pi and 3 cancel on both sides

theta*2/360=1/2

theta/180=2

theta=180/2

Hence theta or the angle required=90 degrees(option C)
