Question

12. A rectangular piece of paper having
length 4.4 cm and breadth 1.5 cm is to
be rolled along its length to form a right
circular cylinder. Find the height and the
volume of the right circular cylinder.
​

Answer 1

Answer:

4.4 length 1.5 breadth 4.4+1.5 =59

Answer 2

Answer:

       Volume = 2.31 cm³           

Step-by-step explanation:

• Height = 1.5cm

circumference of one side - 2πr = 44cm

2 × 22 / 7 × r = 4.4

r = 4.4 × 7 / 2 × 22

r = 0.7cm

• Volume of cylinder = πr²h

        = 22 / 7 × 0.7 × 0.7 × 1.5

       = 2.31 cm³
