Answer:

The correct option is option (A)

The volume of the metallic rod is 60π cm³.

Step-by-step explanation:

Cylinder:

  • It is three dimension shape.
  • The lateral surface area is 2πrh, r= radius, h= height
  • Total surface area = 2πrh+2πr²,
  • Volume = πr²h.

The radius of the base of metallic rod is 2 cm and its height is 15 cm.

Here r= 2 cm, h= 15 cm, \pi =\frac{22}7

The volume of metallic rod is

=πr²h

=π(2 cm)² (15 cm)

=π(4)(15) cm³

=60π cm³

Answer:

A) 60π cm³

Step-by-step explanation:

Given:

The<u> radius </u>of the base of a metallic rod is<u> 2 centimetres</u>, and its<u> height is 15 centimetres.</u>

Question asked:

What is the<u> volume </u>of this cylinder?

<u>Solution</u>:

As we know''

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

                                =\pi \times2\times2\times15\\ \\ =60\pi

Therefore, the volume of this cylinder will be 60\pi\ cm^{3}
