The volume of the solid (cylinder) is 6π unit³,

<h3>Volume</h3>

The volume of an object is the amount of space occupied by a three dimensional object.

A solid with a circular base and a vertical cross section is a cylinder.

Therefore the solid shown in the problem above is a cylinder.

A unit circle has a radius of 1, hence the radius of the cylinder = 1 unit, diameter = 2 * radius = 2 * 1 = 2 unit

Height of cylinder = 3 * diameter = 3 * 2 = 6 unit

Volume of cylinder = π * radius² * height = π * 1² * 6 = 6π unit³

The volume of the solid (cylinder) is 6π unit³.

A cone has a volume of 5 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?
Pie

Answer:

15 in^{3}

Step-by-step explanation:

Given:

Volume of Cone= 5 inch ^{3}

Solution:

Formula:

Volume of Cone =\frac{1}{3} \pi r^{2} h

Volume of Cylinder= \pi r^{2} h

\therefore We can say that

Volume of Cone = \frac{1}{3} \times Volume of Cylinder

\therefore Volume of cylinder = 3 \times Volume of Cone

Now Substituting given data we get

Volume of Cylinder= 3\times5

Volume of Cylinder= 15 in^3
