Answer:

The volume of a cylinder is 62.8 cm and the volume of a cone is 20.9 cm³ .

Step-by-step explanation:

Formula

[tex]Volume\ of\ a\ cylinder = \pi r^{2} h[/tex]

[tex]Volume\ of\ a\ cone = \pi r^{2} \frac{h}{3}[/tex]

Where r is the radius and h is the height .

As given

A cylinder and cone have the same height and radius. The height of each is 5 cm, and the radius is 2 cm.

[tex]\pi = 3.14[/tex]

Thus

[tex]Volume\ of\ a\ cylinder =3.14\times 5\times 2\times 2[/tex]

                                             = 62.8 cm³

Thus the volume of a cylinder is 62.8 cm³ .

[tex]Volume\ of\ a\ cone = 3.14\times 2\times 2\times frac{5}{3}[/tex]

[tex]Volume\ of\ a\ cone =\frac{5\times 3.14\times 2\times 2}{3}[/tex]

[tex]Volume\ of\ a\ cone =\frac{62.8}{3}[/tex]

                                        = 20.9 (Approx) cm³

Thus the volume of a cone is 20.9 cm³ .

Therefore the volume of a cylinder is 62.8 cm and the volume of a cone is 20.9 cm³ .
