The mass of the cylinder made of lead is 644.33 kg.

What is mass?

Mass can be defiend as the quantity of matter a contained in a body. The S.I unit of mass is kilogram (kg).

To calculate the mass of the cylindrical lead, we use the formula below.

Formula:

  • m = πr²hd........... Equation 1

Where:

  • m = Mass of the cylindrical lead
  • h = Height of the  cylindrical lead
  • d = Density of the lead
  • r = Radius of the cylindrical lead
  • π = Pie

From the question,

Given:

  • r = 3/2 = 1.5 cm
  • d = 11.4 g/cm³
  • h = 8 cm
  • π = 3.14

Substitute the values above into equation 1

  • m = 11.4×3.14×1.5²×8
  • m = 644.33 kg

Hence, the mass of the cylinder made of lead is 644.33 kg.
