Question

Points A and B lie on a circle with a radius of 1,

arc AB has a length of pi/6
. What fraction

of the circumference of the circle is the length of arc AB?

Answer 1

Step-by-step explanation:

Lenght of an arc = pi/6

Circumference of the circle = 2×pi × r = 2 pi (r=1 given)

Therefore,

Ratio of AB:Circumference = Pi/6/(2Pi) = 1/12

Thus, AB arc is 1/12 part of the circumference.
