Question

In the figure(2) given below ABC is an equilateral triangle of side 14cm, side BC is the diameter of a semicircle.Find the area of the shaded region. take √3=1.732

Answer 1

radius =d/2=14/2=7cm
Area of semi circle =1/2*22/7*(7*7)
Area of semi circle =11/7*49
Area of semi circle =7*11=77cm2

Area of equilateral triangle =1.732/4*(a2)
Area =1.732/4*(14*14)
Area =1.732/4*196
Area =1.732*49
Area=84.868cm2

Area of shaded region =77+84.868
Area of shaded region =171.868cm2
