Answer:

[tex]V_2 = 200.96cm^3[/tex]

Explanation:

Given

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

See attachment for refraction cup

Required

The volume of the cup

From the attached image, we have:

[tex]h = 2[/tex] --- height of the cup

[tex]d = 8[/tex] --- diameter of the cup

Calculate the radius

[tex]r = 0.5 * d[/tex]

[tex]r = 0.5 * 8[/tex]

[tex]r = 4[/tex]

Calculate the volume of 1 cup

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

[tex]V_1 = 3.14 * 4^2 * 2[/tex]

[tex]V_1 = 100.48[/tex]

The volume of 2 is 2 multiplies by the volume of 1

So, we have:

[tex]V_2 = 2 * V_1[/tex]

[tex]V_2 = 2 * 100.48[/tex]

[tex]V_2 = 200.96cm^3[/tex]
