Area of a sector = (Length of an arc of a sector × Radius of the sector) / 2
Area of a sector = 54 cm2
Radius of the sector = 36 cm
Area of a sector = (Length of the corresponding arc)(Radius of the arc) / 2
54 = (Length of the corresponding arc)(36) / 2
54 = (Length of the corresponding arc)(18)
Length of the corresponding arc of the sector = 3 cm.
Hope This Helps :)
sayantanisingha:
Where will the pi be?
Will it be 3pi cm?
Which pi dear, there is no pi in the whole question and the ans....
Nope, It will be just 3, no 3pi, hope uh get it :)
You have taken just 54 but in the question it's given 54pi so you have to take a pi along with 54
