Answer:

The volume of cylinder L is 4 times the volume of cylinder B

Step-by-step explanation:

step 1

Find the radius of Cylinder B

The volume of a cylinder is equal to

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

we have

[tex]VB=36\pi\ in^{3}[/tex]

[tex]h=4\ in[/tex]

substitute and solve for r

[tex]36\pi=\pi r^{2} (4)[/tex]

Simplify

[tex]9=r^{2}[/tex]

[tex]r=3\ in[/tex]

step 2

Find the volume of the Cylinder L

we have

[tex]h=4\ in[/tex]

[tex]r=2*(3)=6\ in[/tex]

substitute in the formula

[tex]VL=\pi (6)^{2} (4)[/tex]

[tex]VL=4*(36\pi)\ in^{3}[/tex]

[tex]VL=4VB[/tex]

therefore

The volume of cylinder L is 4 times the volume of cylinder B
