Raghu needs to make a cylindrical aluminum tube. What will be the area of the aluminum sheet required to make the tube, if the length and radius of the tube should be 1 m and 3.5 cm respectively [Top and bottom of the tube are of another material]?(use π=227)

Raghu needs to make a cylindrical aluminum tube. What will be the area

1.	Raghu needs to make a cylindrical aluminum tube. What will be the area of the aluminum sheet required to make the tube, if the length and radius of the tube should be 1 m and 3.5 cm respectively [Top and bottom of the tube are of another material]?(use π=227)
Answer» Raghu needs to make a cylindrical aluminum tube. What will be the area of the aluminum sheet required to make the tube, if the length and radius of the tube should be 1 $m$ and 3.5 $c m$ respectively [Top and bottom of the tube are of another material]? ( $u s e π = \frac{22}{7}$ )
