Answer:

V = 1200π

Step-by-step explanation:

Volume of a cylinder formula:

  • V = πr²h

Let's find the height of the cylinder by multiplying 20 cm by 3/5.

  • 20 * 3/5 = 60/5 = 12 cm

The radius is 1/2 of the diameter, so:

  • 20 * 1/2 = 20/2 = 10 cm

Substitute 12 for h and 10 for r into the volume formula.

  • V = π(10)²(12)

Simplify.

  • V = π * 100(12)  
  • V = π * 1200

The volume of a cylinder, in terms of π, is V = 1200π.
