Question

plz find the area of the shaded region​

Answer 1

answer:-1/3 of the shaded region

Answer 2

Answer:SEMI CIRCLE(AB)

AB =diameter=28cm

radius =diameter/2

          =28/2=14 cm

area of semi circle(AB)=1/2$\pi$r²

                                    = 1/2×22/7×14×14

                                    = 22×7×2

                                    = 308cm²

semi circle(AO) & (OB) both are same

radius = 7 cm

area of semi circle= 1/2 $\pi$r²

                               = 1/2×22/7×7×7

                               = 77 cm²

area of two semi circle = 77×2=154cm²

area of shaded part = area of semi circle(AB) - area of semi circle(AO andOB)

                                  =308 cm²-154 cm² =154 cm²

Hence, area of shaded part is 154cm²

I hope that will help you
