hello,
do you know what the formula for volume of cones?

lochana · Answer

if volume is V
$$V = \Pi r^2\frac{ h }{ 3 }$$

lochana · Answer

r is radius (half of diameter) 
h  = altitude

i'm sorry, but can i ask if how did you get the answer?

anonymous · Answer

the other volume will be tripled. You will equate it with the original volume of the cone, then cancel out the height
