A 6 oz paper cup is shaped like a cone with a diameter of 4 inches. How many ounces of water will a plastic cylindrical cup with a diameter of 4 inches hold if it is the same height as the paper cup?

Respuesta :

Answer:

The plastic cylindrical cup will hold 17.96 ounces of water.

Step-by-step explanation:

Given:

A 6 oz paper cup is shaped like a cone with a diameter of 4 inches.

Now, to find ounces of water will a plastic cylindrical cup with a diameter of 4 inches hold if it is the same height as the paper cup.

Volume of cone = 6 oz.

Diameter = 4 inches.

So, radius (r) = [tex]\frac{Diameter}{2} =\frac{4}{2} =2\ inches.[/tex]

Taking the value [tex]\pi[/tex] = 3.14.

Now, to get the height (h) we put formula:

[tex]Volume=\pi r^2\frac{h}{3}[/tex]

[tex]Volume=3.14\times 2^2\times \frac{h}{3}[/tex]

[tex]6=3.14\times 4\times \frac{h}{3}[/tex]

Multiplying both sides by 3 we get:

[tex]18=12.56h[/tex]

Dividing both sides by 12.56 we get:

[tex]1.43=h[/tex]

[tex]h=1.43\ inches.[/tex]

Now, to get the volume of cylindrical cup.

As, given it is the same height as the paper cup.

Height (h) = 1.43 inches.

Diameter = 4 inches.

Radius (r) = [tex]\frac{Diameter}{2} =\frac{4}{2} =2\ inches.[/tex]

So, we put formula to get the ounces of water a plastic cylindrical cup will hold:

[tex]Volume =\pi r^2h[/tex]

[tex]Volume=3.14\times 2^2\times 1.43[/tex]

[tex]Volume=3.14\times 4\times 1.43[/tex]

[tex]Volume=17.96\ oz.[/tex]

Therefore, the plastic cylindrical cup will hold 17.96 ounces of water.
