Depth in CalculusA conical tank (with vertext down) is 10 ft across the top and 12 feet deep. If water is flowing into the tank at a rate of 10ft³/min, Find the rate of change of the depth of the water when the water is 8ft deep. #2 20051015 14:28:29
Re: Depth in CalculusVolume of the concial tank is 1/3*pi*r²*h Character is who you are when no one is looking. #3 20051015 15:43:10
Re: Depth in CalculusThe formula for the volume of a cone is V = (1/3) * (pi * r²) * h. Last edited by ryos (20051015 15:46:35) El que pega primero pega dos veces. #4 20051015 15:55:53
Re: Depth in CalculusHeh, I took too long, ganesh beat me to it. El que pega primero pega dos veces. #5 20051015 16:02:20
Re: Depth in CalculusHey ganesh, I was trying to learn from you , and I found a calculation error:
You forgot to square the 5/12. El que pega primero pega dos veces. #7 20051015 16:41:58

Re: Depth in CalculusSuch as not giving insomnia any boards to mod? Why did the vector cross the road? It wanted to be normal. #9 20051015 21:32:34
Re: Depth in CalculusWell...insomnia said he wanted to be a 'mod'. He never said he wanted to mod.
