What is the volume of the cylinder below use formula v=ñr2 h
Vikki [24]

Answer:

The volume of the cylinder = π r² h

where r is the radius of the cylinder and h is the height of the cylinder.

This is formula is applied for the right cylinder as figure 1 and oblique cylinder as figure2.

<u>The volume of the cylinder of figure 1:</u>

r = 6  and  h = 7

volume = π r² h = π  * 6² * 7 = 252π   units³

<u>The volume of the cylinder of figure 2:</u>

r = 11  and  h = 15

volume = π r² h = π  * 11² * 15 = 1,815π   units³
