In a circular table cover of radius 32 cm, a design is formed
leaving an equilateral triangle ABC in the middle as shown in the
given figure. Find the area of the design (Shaded region).
Radius (r) of circle = 32 cm
AD is the median of
ABC.
AD = 48 cm
In ΔABD,
AB2 = AD2 + BD2
Area of equilateral triangle,
Area of circle = πr2
Area of design = Area of circle − Area of ΔABC
