What is the volume of the cylinder

Harman [31]

The volume of a cylinder is given by

$V = A_b\cdot h$

where $A_b$ is the base area, and $h$ is the height.

We are already given the height, which is 10.

We can deduce the base area since we are given a diameter: the radius is half the diameter, so it's 8, and the area of a circle is given by

$A_b = \pi r^2 = \pi 8^2 = 64\pi$

So, the volume is

$V = A_b\cdot h = 64\pi \cdot 10 = 640\pi \approx 2010.6193\ldots$
