Re: Calculus Question....
It helps if you write it down on a sheet of paper. It is pretty hard to visualise when it is in text like that.
2πrh + πr² + sqrt(2)πr² = Replace h = (15 - πr³) / (3πr²) 2πr((15 - πr³) / (3πr²)) + πr² + sqrt(2)πr² = Simplify the πr in the first term. 2((15 - πr³) / (3r)) + πr² + sqrt(2)πr² = Distribute the 2: (30 - 2πr³) / (3r) + πr² + sqrt(2)πr² = Here, I actually skipped a few steps. Separate the first term into 2. 30 / (3r) - 2πr³ / (3r) + πr² + sqrt(2)πr² = Simplify the first term: 10 / r - 2πr³ / (3r) + πr² + sqrt(2)πr² = Simplify the second term: 10 / r - 2πr² / 3 + πr² + sqrt(2)πr² = Add the second and third term: 10 / r + πr² / 3 + sqrt(2)πr² = Reorder the terms for my OCD: sqrt(2)πr² + πr²/3 + 10/r PS: We should totally have LaTeX. That would make things so much prettier. |

Re: Calculus Question....
In the last step you are adding 1 pi to sqrt(2)piR^2, why doesnt it change?
