Question

find the area of sector of a circle with radius 6 cm if angle of the sector is 60° ?

Answer 1

area of sector = (pie r.r./2pie )× pie/3
= r.r pie/6

= 36pie/6 = 6 pie = 18.84

Answer 2

we know that area A of a sector of angle theta in .


a circle of radius r is given by A = theta / 360 × πr^2


here

r = 6 cm , theta =60°

A= [ 60 / 360 × 22/ 7 × 36] cm^2


(132/7 ) cm^2
