A closed cylindrical tank of radius 7 m and height 3 m is made from a sheet of metal. How much sheet of metal is required?

Given:
Radius $r = 7 m$ , height $= 3 m$

We need to find the total surface area of a cylinder
$= 2 π r (r + h)$

$= 2 \times \frac{22}{7} \times 7 (7 + 3) = 440$ sq meter

So, $440$ sq m sheet of metal is required.

A closed cylindrical tank of radius 7 m and height 3 m is made from a sheet of metal. How much sheet of metal is required?

Given:Radius r=7m, height =3mWe need to find the total surface area of a cylinder=2πr(r+h)=2×227×7(7+3)=440 sq meterSo, 440 sq m sheet of metal is required.
