Look to find the area you need to put the value of radius in the formula:
(pie)r^2
22/7*21*21
1386
and do the same in other
(pie)r^2
22/7*21*21
1386
and do the same in other
sry I didn't wrote full answer but I DoD it because if you want to be good at maths you should try solving questions yourself
HOPE you understand why I did it
I know that and I am agree with that
