Quantitative Aptitude ( CCS) Mensuration 2D

A cow is tethered at point A by a rope. Neither the rope nor the cow is allowed to enter the triangle ABC.

BAC = 30° and AB = AC = 10 m.

What is the area that can be grazed by the cow, if the length of the rope is 8 m?

134π/3 m²

121π m²

132π m²

176π/3 m²

πR²/2
We need to find the sector ACBO.
πAOB = 330o = πR²/2
π= R²/2
11*64π/2= Area of sector ACBO
176/3 m² = Area of sector ACBO
