Question

Choir is selling Pringle Chips to raise money for a field trip. The container has a diameter of 9 inches and a height of 32 inches. Identify the equation that can be used to find the volume of the container.

  1. V = π (9)
  2. V = π (4.5)2(32)
  3. V = π (9)2(32)
  4. V = π (4.5)(32)

hintHint:

The formula of the volume of the cylinder is pi r squared h.

The correct answer is: V = π (4.5)2(32)


    The container will create the structure of the cylinder.  We will use the formula of the volume of the cylinder.
    The formula of  the volume of a cylinder is given by
    V space equals space pi r squared h.
    where r is the radius of the container and h is the height of container.
    we are given the diameter of the container, from that we can find the radius by dividing by 2 and height of the container as 32.
    r equals d over 2
    r equals 9 over 2 equals 4.5
