Question

A solid cylinder of iron with diameter 28cm and height 50cm have mass of 61.6kg. Find the density of the cylinder.​

Answer 1

Answer:

500

Explanation:

Density = Mass/Volume

Mass is given 61.6Kg so we need to find volume of cylinder so after that we can calculate the density of it.

Formula for cylinder's volume = $\pi$$r^{2} h$

r is radius and h is height

diameter is given 28cm so radius is diameter/2

radius = 14cm

volume = 22 * 14 * 14* 50 /7

            = 30800cm^3

Density = 30800/61.6 = 500
