volume of cylinder is =πr2h =3850m
height= 25m
πr2h=22/7×r2×25 =3850
550/7×r2=3850
r2= 3850×7/550
r2=75×7/11
r2=525/11
r2=47.73
r=√47.73
r=6.9089(approx)
height= 25m
πr2h=22/7×r2×25 =3850
550/7×r2=3850
r2= 3850×7/550
r2=75×7/11
r2=525/11
r2=47.73
r=√47.73

How tell me
tell me how my ans is wrong
volume is 3850cm^3
volume is 3850cm^3 and the formula for cylinder it πr^2h
r^2=3850×1/2500×7/22=49/100=7/10
or maine kya likha h
sirf cube ka sign nhi diya
you have not converted the height 25m to cm
ook i find my mistake thanx
welcome
