Answer:
Diameter=7m
Height=4m
so, Radius=7÷2=3.5m
ATQ:
sheet of metal required=Total surface area
=2πr(r+h)
=2×22/7×3.5(3.5+4)
=44×0.5×7.5
=44×3.75
=165.00
=165 m^2

Answer:
Sheet of metal required = 165m^2
Step-by-step explanation:
d = 7m
r = 7/2m (or) 3.5m
h = 4m
Total Surface area of cylinder = 2πr(r + h)
= 2 * 22/7 * 7/2(3.5 + 4)
= 22 * 7.5
= 165m^2
