Answer:

about 3.08 L

Explanation:

You want the number of litres in the volume of a cylindrical can 14 cm in diameter and 20 cm high.

Liters

A litre is a cubic decimeter, 1000 cubic centimeters. As such, it is convenient to perform the volume calculation using the dimensions in decimeters:

  • 14 cm = 1.4 dm . . . . . . diameter
  • 20 cm = 2.0 dm . . . . . height

Volume

The volume of the cylinder is given by the formula ...

V = (π/4)d²h . . . . . . . where d is the diameter and h is the height

V = (π/4)(1.4 dm)²(2.0 dm) ≈ 3.079 dm³ ≈ 3.08 L

The cylindrical can will hold about 3.08 litres.
