Answer:
h = 2.86
Explanation:
Given: Cone; Volume = 12pi, raduis = 2
To find: The height
Formula:
![V= \pi r^2 (h)/(3)](https://img.qammunity.org/2022/formulas/mathematics/high-school/uf7ldrvskgf5m1rc6b26rc4tltcc478lcp.png)
Solution: Triple the volume amount. For this cone, the volume is 12. Multiplying the volume by 3 results in 36.
×
Square the radius, and then divide the radius squared into the tripled volume. The cone's radius is 2. The square of 2 is 4, and 36 divided by 4 is 9.
÷
Divide the resulted amount calculated by pi, which is 3.14, to calculate the cone's height. 9 divided by pi results in 2.86.
÷
![3.14 = 2.86](https://img.qammunity.org/2022/formulas/mathematics/high-school/wt8z4za411httj64fqx8tdkm39r70bx56c.png)
Therefore, the height of this cone is 28.6.
