A cylindrical tube has a radius of 4 inches and a height of 14 inches could some one help me find the volume

pickupchik [31]

The volume of the cylinder is the area of the base (a circle) times the height (you can immagine taking a disk, the base, and translate it along the height to "fill" the cylinder).
So you have:
$V=area.circle*height= \pi r^{2}*h = \pi 4^{2} *14=703.4 in^{2}$
