Given a soda can with a volume of 15 and a diameter of 2, what is the volume of a cone that fits perfectly inside the soda can? (Hint: only enter numerals in the answer blank).

Respuesta :

the volume of the cone will be 1/3  of the can .

that is 5 

Answer:

5 cubic units.    

Step-by-step explanation:

We have been given that a can soda can has a volume of 15 cubic units and a diameter of 2.

First of all let us find the height of cylinder using volume of cylinder formula.

[tex]\text{Volume of cylinder}=\pi r^2 h[/tex], where,

r = radius of cylinder,

h = Height of cylinder.

Now let us divide our diameter by 2 to get the radius of cylinder.

[tex]\text{radius of cylinder}=\frac{2}{2}=1[/tex]

Let us substitute our given values in volume of cylinder formula to get the height of cylinder.

[tex]15=\pi*1^2*h[/tex]

[tex]15=\pi*h[/tex]

[tex]\frac{15}{\pi}=\frac{\pi*h}{\pi}[/tex]

[tex]\frac{15}{\pi}=h[/tex]

Now we will use volume of cone formula to find the volume of our given cone inscribed inside cylinder.

[tex]\text{Volume of cone}=\frac{1}{3}\pi*r^2h[/tex]

Since the height and radius of the largest cone that can fit inside the can will be equal to height and radius of can, so we will substitute [tex]\frac{15}{\pi}=h[/tex] and [tex]r=1[/tex] in the volume formula of cone.

[tex]\text{Volume of cone}=\frac{1}{3}\pi*1^2*\frac{15}{\pi}[/tex]

[tex]\text{Volume of cone}=\frac{1}{3}*1*15[/tex]

[tex]\text{Volume of cone}=5[/tex]

Therefore, volume of our given cone will be 5 cubic units.
