1cc (cubic centimeter) = 1 mL

V = Pi* r

^{2 }* h [cc]convert from [cc] to [L] => [cc] x[1 mL/ 1cc] x [1L/ 1000mL] => [L]

V = 471 L,

(1/2) V = 235.6 L

t = [(1 min) / 12.3 L ] x 235.6 L = 19.2minutes

Hi Sophia;

Our first priority is to establish the volume of the cylinder.

V=(3.14)(r

^{2})(h)3.14 is pie.

V=(3.14)(50 cm)

^{2}(60 cm)V=(3.14)(2500 cm

^{2})(60 cm)V=471000 cc

There are 1000 cc in 1 liter.

We must convert...

V=(471000 cc)(1 liter/1000 cc)

Let's cancel units where appropriate...

V=(471000 cc)(1 liter/1000
cc)

V=471 liters

12.3 l/min is the flow

We need to know minutes.

Therefore, we need to know the minutes/liters.

The inverse of 12.3 liter/min is

0.08 min/liter

(471 liters)(0.08 min/liter)

Let's cancel units where appropriate...

(471 liters)(0.08 min/liter)

37.68 minutes

Halfway=37.68 minutes/2=18.84 minutes

V = π r

V ÷ 2 = 235714.29 cm

235.71 ÷ 12.3 ≈

^{2}h = (22/7)50^{2}60 ≈ 471428.51 cm^{3}*V = 3.14*2500*60 ≈ 471000 cm*^{3}V ÷ 2 = 235714.29 cm

^{3}≈ 235.71 L*V / 2 = 235500 cm*^{3}*(1 m*^{3}= 1000 L or 1000 cm^{3}= 1 L)235.71 ÷ 12.3 ≈

**19.16 minutes**

235.5 / 12.3 ≈ 19.14

Sophia, if you solve problems online, computer usually suggests the value of π "pi" 3.14 or 22/7 and till what place value you have to round your answer. If you do not follow those recommendations, computer will mark your answer as wrong one.
