During a chemistry lab, you use a funnel to pour slime into a flask. The radius of the funnel is 4 cm and the height is 12 cm. You pour the slime into the funnel at a rate of 60 mm per second and the slime flows out of the funnel at a rate of 40 mm per second. How long will it be before the funnel overflows with slime? Note: 1 mm is equal to 1 cubic centimeter. you do NOT need to do any conversions for this problem

First ,   1 mm   does NOT equal 1 cc        1 ml   does equal 1 cc.

             one is a length....the other is a volume.

Second 

     Volume of funnel = 1/3 pi r^2 h

                                = 1/3 pi 42 12 = 201  ml

 

 

    NET volume going into the cone is (I assume ml   NOT mm )    60-40  = 20 ml per second

              201 ml / 20 ml/sec = ~~ 10 seconds
