Question

Word problem what am I doing wrong. (work shown coming)

Answer 1

\[Π(15)^2(h−15)+\frac{ 1 }{ 2 }(\frac{ 4 }{ 3 }Π(15)^3)\]

I work it out and get 51

Answer 2

\[225\Pi(h-15)+\frac{ 2 }{ 3 }(3375) = 12600\Pi\]

I divide by pi on both sides to get ride of it and work out the next step and get

\[225h-3375+2250=12600\]

add them all up and divide by H and get 51

Answer 3

I'm using what I think is the same equation as yours:

pi*225*(h-15) + (1/2)*((4/3)*pi*15^3) ) = 12600*pi

and got 61 for h. See what you think. @cronus8992

Answer 4

I did receive 61 the second time but cannot figure out where my error was the first time to receive 51
