Answer 1

Hi friend ,
here is ur solution:-
vrittakar raste ka bahri ghera = 20π
aur bhitari ghera = 12π
kyun ki vrit ki paridhi = 2πr
isliye 2πr = 20π
r = 10m
arthat bahri ghere ki trijya = 10 m
isi prakar bhitari ghere ki trijya =
2πr = 12π
r = 6m

atah
raste ki chaudai = 10-6 = 4m ans
I hope it'll help u.
Thanks
