Question

The iron cylinder have 3 metre radius and 7 length mass the iron cylinder is is 396 grams what is relative density of iron cylinder

Answer 1

Answer:

2 cm^3 / g

Explanation:

Volume of the cylinder = Pi r^2 h

= 22 / 7 * 3 * 3 * 7

= 198 cm ^3

Now density = mass/volume = 396 / 198

= 2 cm^3 / g
