Hi,
Dimensions of required right circular
cylider is ,
Diameter (d) = 4m
Radius (r)= d / 2 = 4 / 2 = 2m
Height of the cylinder ( h )= 10m
Area of the iron sheet required
to make right circular cylinder
= Curved surface area of the cylinder
= 2πrh
= 2 × (22/7) × 2 × 10
= 880 / 7 m
= 125.71 m
I hope this helps you.
