- if 12.3 L per min will flow through a water faucet.

Hi Sophia;

V=(3.14)(r

^{2})(h)3.14 is pie

Since this is "halfway"...

V=(0.5)(3.14)(50 cm)

^{2}(60 cm)V=235500 cc

1000 cc = 1 liter

(1 liter/1000 cc)(235500 cc)

Let's cancel units where appropriate...

(1 liter/1000 cc)(235500
cc)

235.5 liters

The flow is 12.3 liters/minute.

We need minutes/liters.

(1)/(12.3 liters/minute)=0.08 minutes/liter

(235.5 liters)(0.08 minutes/liter)

Let's cancel units where appropriate...

(235.5 liters)(0.08 minutes/liter)

18.84 minutes
