find the area of a circle inscribed in an equilateral triangle with sides of length 20 cm
If the side is 2 sqrt(3), then the radius is 1
Since side =20 radius = 20/(2*sqrt(3)) =10 *sqrt(3)/3
Area of the circle = pi* 10^2*3/9= pi*100/3 =3.14*100/3 =314/3 =104.67 sq cm
Answer: 100/3*pi or 104.67 sq cm
