# write the formula for the area of a segment in a circle, a circle of radius r, given that the sector angle is theta (in degrees). the answer to this is [pi theta/360- sin theta /2 cos theta /2] r2 as given in r.d. sharma. I can't understand how the formula derived.....experts plzzz help me in dis question.....

Given: A circle with center O of radius r. ∠AOC = θ and ∠AOD =

To find: Area of segment ABC.

Solution:

Area of segment ABC = area of sector OABC – area of ΔOPQ

The area of sector OABC =

Hence proved.
