Question 169862
Calculate the volume of a cylinder with a diameter of 6 inches and a height of 16 inches. Round answer to the nearest cubic inch. 
The answer I came up with is 1808.64 which doesn't seem correct.
------------
{{{V = pi*(r^2)*h}}}
{{{V = pi*9*16}}}
V = 144*pi
V = 452 cubic inches
-------
You probably used the diameter, not the radius.
