Question

A liquid spray of 384g is packed in a cylindrical container of internal radius 3.2cm. Given that the density of the liquid is 0.6g/cm³, calculate to 2 decimal places the height of the liquid in the container.

Answer 1

Mass of spray = 384
Intense radius =3.2
Density of = 0.6g/lcm²
V= M/D= 384g/0.6glc= 640cm³
Volume of the cylinder= π²h
π²h= 640
3.142x 3.22 h= 640
h₂=         640          =          640         
          3.142x 3.22        3.142 x 10.24
= ⁶⁴⁰/_32.17408
=19.891789
= 19.89cm
