Fast pls!

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

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)

a: 1/6, j: 1/4
