A sector of a circle of radius 9cm subtends angle 120 degree at the circle. Find the area of the sector.
SOLUTION
radius=9cm
pie=22/7
titer=120
Area of sector=titer/360 x pie radius square.
=120/360 x 22/7 x 9square
=120/360 x 22/7 x 81
(Zero cancel zero)
=12/36 x 1782/7
=21384/252
=84.8(approximately)

titer? where ever did you get that?
The Greek letter θ is <u>theta</u>
oh, and π is <u>pi</u>, not pie!
