220÷2=110cm=1.1m radius,
height=2m
surface area of cylinder=2pier^2
2×22/7×1.1×2
13.828cm^2

Height = 200cm
2pi r = 220cm
pi r=220÷2
r=110÷22/7
r=35cm
TSA=2pi r(h+r)
2×22/7×35(200+35)
220(235)
=47000cm^2
This answer is correct.
Above one don't know that cylinder have a circular base
Therefore, 2pi r=220cm
2pi r = 220cm
pi r=220÷2
r=110÷22/7
r=35cm
TSA=2pi r(h+r)
2×22/7×35(200+35)
220(235)
=47000cm^2
