Question

Find the area of shaded region, if Ao=14cm and Bo=7cm​

Answer 1

Answer:

Given

Ao =14cm

Bo =7cm

AB = Ao+ Bo

=14 + 7 =21

Area of a circle =πr×r

Area of big circle = πr×r =22/7×21×21

= 1386 sq.cm

Area of two small circles = πr×r +πr×r

=22/7×14×14 +22/7×7×7

= 616 + 154

=770sq.cm

Area of the shaded region = Area of big circle + Area of two small circles

= 1386 sq.cm +770 sq.cm

=2156sq.cm

Area of the shaded region = 2156sq.cm
