• ### Sand falls from a conveyor belt Math Central

So we turn to the equation for the volume of a cone: V = 1/3 (pi) r 2 h. Since the radius of the base always equals half the height, we have r = (h/2), so the equation for the volume becomes V = h 3 / 12. 2) Differentiate the equation with respect to time. This will relate the rates.

### 14. Solution Trinity College Dublin

We know that the sand falls from a conveyor belt at the rate of 10 m 3/min (10 m per minute), so dV dt = 10 m3/min. Hence: (a) Substituting dV dt = 10 and h= 4 into equation (*) yields 10 = 16ˇ 4 2 9 dh dt, so dh dt = 90 256ˇ ˇ 11:19 cm/sec. (b) Since r= 4h 3, we have dr dt = 4 3 dh dt = 4 3 90 256ˇ = 15 32ˇ ˇ14:92 cm/sec. 19. Water is
