22/7radius of cone is 0.1 m
volume is cone =1/3*22/7*0.1*0.1*0.4
88/21000m^3
vol of sphere=4/3*r^3
88/21000=4/3*r^3*
88/21000*3/4*7/22=r^3
1/1000=r^3
r=1/10
r=0.1 m
hence radius of the sphere would be 0.1 m

r= 10 cm
I hope you can understand
write in mathematical form
then you can understand perfectly
ok
Thank you!
ok
u understand very well
I think
oh hello 10 centimetre equals to 0.1 M Hota Hai
