  • The volume of a cylinder can be calculated by multiplying the area of a circular face by the length of the cylinder
  • The formula for the volume of a cylinder is: volume = area of circle * length
  • The area of a circle is equal to pi * r^2
  • The volume of a cylinder can also be calculated using the formula: volume = pi * r^2 * length
  • In order to calculate the volume of a cylinder, you need to know the radius and length of the cylinder
  • The volume of a cylinder can be calculated in one step using the formula, or in two steps by calculating the area first and then multiplying by the length
  • In the example given, the radius of the circular base is 3cm and the length is 10cm
  • The area of the circular base is calculated as pi * 3^2 = 9pi
  • The volume of the cylinder is then calculated as 9pi * 10 = 283cm^3 (to three significant figures)
