A water tank has the shape of an inverted circular cone with base radius 2 m and height 4 m . If water is being pumped into the tank, and at certain time
t_(0)!=0
, the volume of the water
V
is given by
V=(1)/(3)\pi r^(2)h,
where
r
is the radius of the surface and
h
is the height of the water at a specific time during the pumping process. it is very useful to express
h
as a runction of
h,V(h)
alone. a. Find the expression
V(h)
. (Hint Think of similar triangles)ok
