sheet required = total surface area
we have h=1m and r=0.6m i.e 6/10
total surface area of cylinder=2πr(h+r)
2x 22/7x6/10(1+0.6)
=2*17*3*166/175
=6.03cm square

Answer: 6.03328
Step-by-step explanation:
height=1m, diameter base 120cm,
radius=120/2=60cm
we know that:1m=100cm
height=1m=1*100=100cm
Surface area of cylinder=2πr(r+h)
Surface area of cylinder
=2*22/7*60cm(60cm+100cm)
=60332.8cm^2
convert: 60332.8cm^2 into m
so, 60332.8/10,000 m
=6.03328m
