What could you do to the volume of a cylinder to get the volume of a cone with the same circular face? Multiply by 3. B Divide by 3. Multiply by 4. Divide by 4.​

Respuesta :

Answer:

The volume of a cylinder must be multiplied by 1/3 or divided by 3 to get the volume of a cone

Step-by-step explanation:

Volumes

Given a cylinder of radius r and height h, its volume is calculated with the formula:

[tex]\displaystyle V_{cy}=\pi r^2h[/tex]

On the other hand, the volume of a cone with the same dimensions is:

[tex]\displaystyle V_{co}=\frac{1}{3}\pi r^2h[/tex]

The ratio between them is:

[tex]\displaystyle \frac{V_{co}}{V_{cy}}=\frac{ \frac{1}{3}\pi r^2h}{ \pi r^2h}[/tex]

Simplifying:

[tex]\displaystyle \frac{V_{co}}{V_{cy}}=\frac{1}{3}[/tex]

Cross-multiplying:

[tex]\displaystyle V_{co}=\frac{1}{3}V_{cy}[/tex]

The volume of a cylinder must be multiplied by 1/3 or divided by 3 to get the volume of a cone
