Answer:
259.87
Step-by-step explanation:
area= area of smaller semi circle of diameter 21cm^
= 1/2 *22/7 * 10.5/2* 10.5/2
=11/7*10.5/2*10.5/2
=5.5*1.5*5.25=43.312m^2
area of bigger circle =πr^2
=346.5m^2
area of shaded region = area of bigger circle _ area of 2 small circles
=346.5_ 86.64
= 259.87m^2
I hope you understand it.
