A liquid spray of 384g is packed in a cylinder 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

  

Answers


Slavin
Volume=mass÷density.
=384g÷0.6g/cm³
=640cm³
but volume of a cylinder =pr²h
therefore ;
640cm³=22/7×3.2cm×3.2cm×h
h=(640cm³ ×7) ÷ (10.24cm² ×22)
hence h= 19.89cm ( 2d.p).
