Question

In the figure,arcs of equal radius of 14 cm.are drawn at each vertex of a equilateral traingle.Find the area of shaded region​

Answer 1

Which is the shaded region??????

Answer 2

sum of angles of a triangle=180°

each angle of an equlateral is60°

ar(semi-circle)=πr^2/2

ar(triangle)=√3/4a^2

ar(shaded region)=-√3/4a^2πr^2

=22/7×14×14×1/2-√3/4×784

=99225.72666
