Answer:
area of the shaded portion = 60.75Πcm2
Step-by-step explanation:
area of small semi circle :
r= 9cm
area of semi circle= 1/2Πr2
= 1/2 Π × 9×9
= 81Π/2
we are having two small semi circle
therefore, 81Π/2+81Π/2
= 81Πcm2
area of small circle:
r= 4.5 cm
area of circle = Πr2
= 20.25Πcm2
area of big semi circle:
r= 18
a= 1/2Πr2
= 1/2Π×18×18
=162Π
area of shaded portion= area of big semi circle - area of 2 small semi circle - area of small circle
= 162Π-81Π-20.25Π
= 60.75Π cm2
