Respuesta :
The volume, V of any cylinder is given by:
[tex] V=\pi r^2h [/tex]
Where, r is the radius of the cylinder
h is the height of the cylinder.
In our case, the radius of the cylinder is 21 centimeters and it's height is 30 centimeters. Therefore, it's volume will be:
[tex] V=\pi(21)^2\times 30=13230\pi cm^3 [/tex]
Thus, the answer answer, in terms of π is [tex] 13230 \pi [/tex] cm³.
