Find the area of the shaded region in the given figure, where a
circular arc of radius 6 cm has been drawn with vertex O of an
equilateral triangle OAB of side 12 cm as centre.
We know that each interior angle of an equilateral triangle is of measure 60°.
Area of sector OCDE
Area of
Area of circle = πr2
Area of shaded region = Area of ΔOAB + Area of circle − Area of sector OCDE
