leaking water problem

I'm stuck please help me... thanks

Didn't they also give you the water level in the tank? I think you need that as well.

chemic_23

no, they didn't :(

Dick

It isn't labelled in a diagram or anything? Their mistake, I think. Then suppose the water level of the tank is L above the vertex (you can plug in the number for L later). Can you express the rate in terms of L?

chemic_23

v=1/3 pi r^2h

substitute r= 3h/2

V= (3pi h^3)/4

d/dt ( V = (3pi h^3) / 4 )

R= (27pi/8)h^2 + 0.5

is this right?

Dick

Looks fine to me.
