A=6. I think that is the answer
** where "r" is radius and "h" is height **

as it refers to the volume of cone being 1/3 of the the volume of cylinder
Hardest, example:
given height of cone is 69 km and radius is 48 km
using the formula:



first thing you have to do is find the rate for the bike so you divide 30 by 2 and you get 15 after you do that you make a problem to find the percentage so you take x/100 and 12/15 then you take 12 times 100 and that gives you 1200 then you divide by 15 and get 80. So the answer is 80%
