Question

Find the density of a material of a Celinda which radius is 2cm,h=4cm,if the mass of the Celinda is 36kg what is the density and what is the material likely to be made off

Answer 1

Answer:

Density = mass/Volume

first we need to figure out the pedestal area

$\pi r^{2}$ ⇒ 3.14 × 4cm = 12.56cm^2

now the volume is h × area

Volume = 12.56cm^2 × 4 = 50.25

36000g/50.25 = 716g/ml or 716g/cm^3
