Question

GEOMETRY FIND THE LENGTH OF AB. LEAVE YOUR ANSWER IN TERMS OF PI

Answer 1

Length of arc (AB)= Central angle* Radius
= 20*π/180*27
= 3π/10

Answer 2

3

Explanation:

The length of the arc AB is equal to the circumference times the fraction of the circle

AB = 2*pi*r * (degrees/360)

AB = 2 * pi* (27) * (20/360)

= 54 * pi * (1/18)

= 3 pi
