I feel like CPhill and the people on the leaderboard except EP are like not active at all, also I see some users are not on the leaderboard, even though they have a lot of likes, is it because they are not active, or quit this forum...????

I realize that we don't have a lot of emoji here on the site.

Apple emoji is the best!

Volume of cylinder = pi r² h if h is increased by 1.4

r will have to decrease to 1.4 r^2 = 1

r = 84.5 per cent of original or decreased by 15.48%

18 people, 11 GOP, so 11/18 ~= 61%.

If you don't understand anything feel free to ask!

Eh no 50% of my answers are something along the lines of "STOP CHEATING" or "this is an AoPS question"

LOL

Good to have you here on this forum. You have been a huge help these past few weeks.

Why are you not smart? because you haven't quite reached the level einstein, newton, and marie curie have reached...

Happy Birthday!!!

Volume of a cone formula v= 1/3 pi r^2 h

You are given volume = 16 pi

you are given h

16 pi = 1/3 pi r^2 ( 12) Divide both sides by pi

16 = 1/3 r^2 (12) 1/3 * 12 = 4

16 = 4 r^2 divide both sides by 4

4 = r^2 I am not going to tell you the answer, I am pretty sure you can do this by yourself here, guest^m^

Hi Sarvajit,

You're on the right track! What you have to subtract is the number of paths from (0,0) to (5,7) that pass through (4,3). To calculate this, all you have to do it multiply the number of paths from (0,0) to (4,3) by the number of paths from (4,3) to (5,7).

I think you can do the rest!

Tell me if you need any help!

:)
