Question:
Karina has recently begun kickboxing and purchased training equipment as modeled in the diagram below. The cylindrical base is 15 inches tall with a diameter of 22 inches.
Karina wants to fill the base so that it is 85% full. What is the volume of the base that she is filling? (Find 85% of the volume).
Answer:
![Section = 4847.3205\ in^3](https://tex.z-dn.net/?f=Section%20%3D%204847.3205%5C%20in%5E3)
Step-by-step explanation:
Given
-- height
-- diameter
Required
85% of the volume
First, calculate the radius
![r = \frac{1}{2} * d](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20d)
![r = \frac{1}{2} * 22= 11in](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%2022%3D%2011in)
The volume (V) is then calculated using:
![V = \pi r^2h](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20r%5E2h)
![V = 3.142* 11^2 * 15](https://tex.z-dn.net/?f=V%20%3D%203.142%2A%2011%5E2%20%2A%2015)
![V = 5702.73\ in^3](https://tex.z-dn.net/?f=V%20%3D%205702.73%5C%20in%5E3)
85% of the volume is:
![Section = 85\% * V](https://tex.z-dn.net/?f=Section%20%3D%2085%5C%25%20%2A%20V)
![Section = 85\% * 5702.73\ in^3](https://tex.z-dn.net/?f=Section%20%3D%2085%5C%25%20%2A%20%205702.73%5C%20in%5E3)
![Section = 4847.3205\ in^3](https://tex.z-dn.net/?f=Section%20%3D%204847.3205%5C%20in%5E3)
