Question

find the area of shaded region​

Answer 1

Area of circle πr²

big c. radius is 4.5/2 is 2.25

area is (pi) *(2.25)² is 15.910

area of small semicircle is( pi * 3² )/2 is

14.142.

area of two remaining circle will be same because the diameter is same. as the diameter is same the radius will also be same.

area of big semicircle is(( pi*2.25²)/2)

is 7.995

sum of the( inner 2 circle and a big circle area) is 44.194

sum of the ( big semicircle and outside semicircle) is 22.137.

so that ( inner 2 circle and a big circle area ) - ( big semicircle and outside semicircle ) is 44.194-22.137 is 22.057 cm² approximately
