Question
A chord of radius 12cm substend an angle of 150°at the centre of the circle.find the area of the segment bounded by the chord and the Minor Arc
Answers
The sector has area 1/2 r^2 θ
The triangle has area 1/2 r^2 sinθ
So the segment has area 1/2 r^2 (θ-sinθ)
The triangle has area 1/2 r^2 sinθ
So the segment has area 1/2 r^2 (θ-sinθ)
