Answer:

  • 127.17 cubic inches
  • 2.25 times

Step-by-step explanation:

You want to know the volume of a cylindrical container 6 inches in diameter and 4.5 inches high, and you want to know how many times larger this volume is than if the diameter were 4 inches.

Volume

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

  V = πr²h

where r is half the diameter, and h is the height.

The volume of your large popcorn container is ...

  V = 3.14·(3 in)²·(4.5 in) = 127.17 in³

The volume of the large container is 127.17 in³.

Ratio

For a given height, the volume ratio is the square of the ratio of diameters. That ratio is given as 3/2, so the volume ratio is ...

  (3/2)² = 9/4 = 2.25

The large container is 2.25 times the volume of the small container.
