Solution -
The question is talking about a closed cylinder means we have to find it's total surface area
∵ Total Surface Area of cylinder
= 2πr(r + h)
∴ Total Surface Area of given cylinder
= [ 2 × 22/7 × 7(7 + 3) ] m² [∵ π = 22/7]
= [ 44 × 10 ] m²
= 440 m²
∴ We need 440 m² of metal sheet to cover the given cylinder

Given =
Radius of the cylindrical tank = 7 m
Height of that tank = 3 m
Now ,
The metal sheet required to make it =
Its total surface area =
= 2πr (r+h)
= 2 × 22/7 ×7 (7+3)
= 2×22/7 ×7× 10
= 2× 22× 10
= 440 m²
The area of the sheet required is 440 m² .
Radius of the cylindrical tank = 7 m
Height of that tank = 3 m
Now ,
The metal sheet required to make it =
Its total surface area =
= 2πr (r+h)
= 2 × 22/7 ×7 (7+3)
= 2×22/7 ×7× 10
= 2× 22× 10
= 440 m²
The area of the sheet required is 440 m² .
thanks
yes use total surface area of vylinder
thanks
yes
because it is closed
