Volume of Pyramids, Cones, and Spheres

The volume of a cone with a radius of 6 cm and a height of 10 cm is

• $30\pi\ cm^3$

• $40\pi\ cm^3$

• $120\pi\ cm^3$

• $360\pi\ cm^3$

The volume of a sphere with a radius of 3 cm is:

• $9\pi\ cm^3$

• $12\pi\ cm^3$

• $36\pi\ cm^3$

• $72\pi\ cm^3$

The volume of a regular hexagonal pyramid with a base edge of 4 inches and a height of 8 inches is:

• $256\sqrt{3}\ in^3$

• $192\sqrt{3}\ in^3$

• $128\sqrt{3}\ in^3$

• $64\sqrt{3}\ in^3$

The volume of a sphere with a diameter of 12 feet would be:

• $2304\pi\ ft^3$

• $288\pi\ ft^3$

• $144\pi\ ft^3$

• $72\pi\ ft^3$

If the surface area of a sphere ( $SA=4\pi r^2$ ) is  $324\pi\ in^2,$  then the volume is: 

•  $27\pi\ in^3$  

•  $108\pi\ in^3$  

•  $243\pi\ in^3$  

•  $972\pi\ in^3$
