area of circle c(o,r) small circle inscribed in dig one= π r² where r=3.5 cm
area = 22/7 ×3.5×3.5=38.5 cm².
area = 22/7 ×3.5×3.5=38.5 cm².

THE SHADED REGION IS NOT ONLY THAT

THIS IS THE CONTINUATION........
area of the semicicle ABCO is
π r²/2=(22/7*7*7)/2
=77 cm²
area of ΔABC=1/2 bh
=1/2*7*14
=49
∴area of shaded region = 77-49=28cm²
area of total shaded region=28+38.5
=66.5cm²
hope this helps you........mark as brainliest pls and say thanks
