Question

A rectangular sheet of metal has length 44cm and breadth 10cm .It is folded to form a cylinder with breath becoming the height. calculate;
1)the radius of the cylinder formed
2) the volume of the cylinder formed ​

Answer 1

Answer:

If a rectangular sheet is folded along its length into a cylinder then it's length will be circumference base of cylinder. So, the meaure of radius of cylinder is 7 cm and height is 10 cm

Answer 2

Step-by-step explanation:

Radius = 7 cm ✬

✬ Volume = 1540 cm³ ✬

Step-by-step explanation:

Given:

Length and breadth of rectangular sheet of metal is 44 and 10 cm respectively.

Sheet is folded along with breadth such that breadth became height of cylinder.

To Find:

What is radius and volume of cylinder?

Solution: If a rectangular sheet is folded along its length into a cylinder then it's length will be circumference base of cylinder.

Now,

★ Circumference of Cylinder = 2πr ★

➫ 2πr = 44

➫ 2 \times× 22/7 \times× r = 44

➫ 44r/7 = 44

➫ r = 44(7)/44

➫ r = 7 cm

So, the meaure of radius of cylinder is 7 cm and height is 10 cm.

[ Finding volume ]

★ Volume of Cylinder = πr²h ★

22/7 × 7² × 10

\implies{\rm }⟹ 22 × 7×10

⟹ 1540 cm³

Hence, Volume of Cylinder is 1540 cm³.
