We know that the volume of the cylinder is given by:

V = r^2* pi * h   such that:

V is the volume, r is the radius, and h is the height of the cylinder.

Given the height h= 12

==> V = r^2 * pi * 12

Now we need to determine the radius r.

But we know that the area of the base is given by>

A = r^2 * pi = 14

Then we will substitute with 14 .

==> V = 14*12 = 168

Then, the volume of the cylinder is 168 cubic units.

What is the volume of the cylinder if the height is 12 and the area of the base is 14.

The volume v of the cylinder is given by:v = pi*r^2*h, where r = radius of the cylinder and h is the height of the cylinder.

Area A of the base of the cylinder is given by: A = pi*r^2 = 14 (given).

Therefore r = (14/pi)^(1/2). We substitute this value of r in the volume v = pi*r^2*h,

v = pi*{(14/pi)^(1/2)}^2*(12), as h = 12 by data.

v = 14*12

v = 168 cubic units.

Therefore the volume of the cylinder is 168 cubic units.
