The volume of a cylinder is 720 and the height is 12. What is the circumference of the base?

Given the volume of a cylinder is 720 and the height is
12.

We need to find the circumference of the
base.

First we will need to determine the radius of the
base.

We will us the volume formula to find the
radius.

We know that V = r^2 * pi * h =
720

==> r^2 * pi * 12 =
720

==> r^2 = 720/12pi = 19.1
(approx.)

==> r=
4.37

Now we will calculate the circumference of the
base.

We know that C = 2* pi * r = 2* pi * 4.37 = 27.46
units ( approx.)

Then the circumference of
the base of the cylinder is 27.46 units.
