Answer:

The volume of the cylinder is 90 cubic inches. Choice E

Step-by-step explanation:

The Volume of a Cone and a Cylinder

Given a cone of radius r and height h, the volume is calculated as:

[tex]\displaystyle V_{cone}=\frac{1}{3}\cdot \pi r^2h[/tex]

If we have a cylinder with the same dimensions, the volume is:

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

Substituting from the first formula:

[tex]V_{cyl}=3V_{cone}=3*30[/tex]

[tex]V_{cyl}=90[/tex]

The volume of the cylinder is 90 cubic inches. Choice E
