+102 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
+36915 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
