Question

A rectangular sheet of paper 44 cm × 24 cm is folded along the length and breadth one by one to form a cylinder. find the radius of cylinder 9f in both the cases ratio of the volume of the cylinder

Answer 1

Answer:

3.81 cm, 7 cm, 3696 cm³

Step-by-step explanation:

Taking circumference as 24 cm:

C= 2πr

24 = 2 * 22/7 * r

r =×$\frac{24 * 7 }{2 * 22}$

= 3.81 cm

Taking circumference as 44 cm:

r = $\frac{44 * 7}{ 2 * 22}$

= 7 cm

Volume of cylinder in both cases = π r² h

Taking radius as 7 cm and height as 24 cm,

vol. = 22/7 × 7 × 7 × 24

= 3696 cm³
