Think of the two pieces together as a single cone of height 19, and its volume.
Then think of only the upper piece as a cone, and find its volume.
The volume of the frustum is the total volume minus the volume of the upper piece.
The volume of a cone is:
![V = \dfrac{1}{3} \pi r^2 h](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cdfrac%7B1%7D%7B3%7D%20%5Cpi%20r%5E2%20h%20)
Total volume:
![V_t = \dfrac{1}{3} \times \pi \times 7.5^2 \times 19](https://tex.z-dn.net/?f=%20V_t%20%3D%20%5Cdfrac%7B1%7D%7B3%7D%20%5Ctimes%20%5Cpi%20%5Ctimes%207.5%5E2%20%5Ctimes%2019%20)
Volume of upper cone:
![V_u = \dfrac{1}{3} \times \pi \times 3.5^2 \times 8](https://tex.z-dn.net/?f=%20V_u%20%3D%20%5Cdfrac%7B1%7D%7B3%7D%20%5Ctimes%20%5Cpi%20%5Ctimes%203.5%5E2%20%5Ctimes%208%20)
Volume of frustum:
Step-by-step explanation:
In order to use the elimination method, you have to create variables that have the same coefficient—then you can eliminate them. Multiply the top equation by 5. Now multiply the bottom equation by −3. Next add the equations, and solve for y.
