Answer:
Area of the shaded part is 3.14 square unit.
Step-by-step explanation:
Area of the shaded part = Area of large semicircle - (Area of two small semi circles)
Area of large semicircle with center O =
=
= 2π
Area of semicircle with center O' =
=
Area of semicircle with center O" =
Now substitute these values in the formula,
Area of shaded part =
=
= 3.14 square unit
Area of the shaded part is 3.14 square unit.
