   Given data

   • Diameter = 4.2cm
   • Density = 8.9cm

   To find

   • Mass of the Ball = ?

   Solution

   As we know that

   radius = Diameter/2 = 4.2/2 = 2.1cm

   Now,

   Density = Mass / Volume

   Mass = Volume × Density

   Volume = 4/3 × pie × r³

   = 4/3 × 2.1 × 2.1 × 2.1

   Mass= 8.9 × 2/3 × 2.1 × 2.1 × 2.1 × 3.14

   Mass = 345.77 gram.
