Ok.

The volume of a cone is the volume of a cylinder over 3.

The volume of a cone is:
$\frac{1}{3} \pi r^{2}h$

This problem gives us the diameter, which is twice of the radius. So, we'll just half it.
Radius (me) = 4 cm.

Substitute our given values into the equation.
$\frac{1}{3} \pi (4)^{2}h \ or \ \frac{1}{3} \pi (4)^{2}(10) \ or \ \frac{1}{3} \pi (16)(10)$

Multiply
$\frac{1}{3} \pi(160) \ or \ \frac{1}{3} (3.14)(160) \ or \ 1.047(160)$

Multiply
$167.52 \ cm^{3}$

This would make $167 \ cm^{3}$ the closest option.
