What is the difference in volume between a cylinder with radius x and height x and a cube with a side of 2x? Let pi = 3.14.

(Volume of cylinder = V = [tex] \pi [/tex]r^2h or V = Bh)

The cylinder:

r = x, h = x

substitute:

[tex]V_1=\pi\cdot x^2\cdot x=\pi x^3\approx3.14x^3[/tex]

The cube:

V =Bh → V = a²· a = a³

a = 2x

substitute:

[tex]V_2=(2x)^3=2^3x^3=8x^3[/tex]

Difference:

[tex]V_2-V_1=8x^3-3.14x^3=4.86x^3[/tex]

Answer: 4.86x³
