Answer:
A) 60π cm³
Step-by-step explanation:
Given:
The radius of the base of a metallic rod is 2 centimetres, and its height is 15 centimetres.
Question asked:
What is the volume of this cylinder?
Solution:
As we know''
[tex]Volume\ of\ cylinder=\pi r^{2} h[/tex]
[tex]=\pi \times2\times2\times15\\ \\ =60\pi[/tex]
Therefore, the volume of this cylinder will be [tex]60\pi\ cm^{3}[/tex]
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, [tex]\pi =\frac{22}7[/tex]
The volume of metallic rod is
=πr²h
=π(2 cm)² (15 cm)
=π(4)(15) cm³
=60π cm³
