Question

if two rectangular sheets with dimensions of (x,2) (y,2) for the curved surface of two different cylinder with two units as the height of the cylinder when the ratio between quotient of the volume v1/v2 and the quotient of the area of the curved surface hi/h2 of the two cylinder is​

Answer 1

Answer: When breadth becomes the curved surface:

Height=22 cm

2πr=10

∴r=

(ii) When length becomes the curved surface:

Height=10 cm

2πr=22

∴r=
