Answer:
[tex]Amount = 55440in^3[/tex]
Step-by-step explanation:
Given [Missing piece]
[tex]h = 9in[/tex] --- height
[tex]r = 7in[/tex] --- radius
[tex]n = 120[/tex] --- number of cones
Required
How much foam for 120 cones
First, calculate the volume of 1 cone
[tex]V = \frac{1}{3}\pi r^2h[/tex]
[tex]V = \frac{1}{3} * \frac{22}{7} * 7^2 * 9[/tex]
[tex]V = \frac{1}{3} * 22 * 7 * 9[/tex]
[tex]V = 22 * 7 * 3[/tex]
[tex]V = 462in^3[/tex]
So, the amount of foams needed for 120 is:
[tex]Amount = 120 * V[/tex]
[tex]Amount = 120 * 462in^3[/tex]
[tex]Amount = 55440in^3[/tex]
