<PRE><B>Question 986240</B>
1 inch = 2.54 cm
12 inches = 1 foot


Just to recheck your cone length part,
h for the length,
{{{r^2+h^2=11.5^2}}}
{{{h^2=11.5^2-r^2}}}
{{{h=sqrt(11.5^2-1.2^2)}}}
{{{h=11.4372}}}, good value for your result.


Be sure to convert your volume for ALL THREE DIMENSIONS.

V for volume,
{{{V*cm^3*(1/2.54)^(3)(inch/cm)^(3)(1/12)^(3)(foot/inch)^(3)}}}</PRE>
