Homework Statement
An inverted right circular cone of vertical angle 120 is collecting water from a tap at a steady rate of 18∏ cm^3/min. Find
a) the depth of water after 12min,
b) rate of increase of depth at this instant
Homework Equations
The Attempt at a Solution
All I know is that dV/dt = 18cm3/min
so shouldn't the depth after 12 mins be 12 * dv/dt?
