Answer:

1,000 cc = 1 liter

Volume of a cylinder = PI * radius^2 * height

(the "cylinder volume" is for one second of "flow")

Volume of a cylinder per sec = 3.14159 * 3.5^2 cm * 5 meters

Volume of a cylinder per sec = 3.14159 * 3.5^2 cm * 500 cm

Volume per second = 19,242 cubic cm which equals

19.242 liters

There are 60 seconds in a minute, so that means the volume per minute =

(19.242 * 60) = 1,154.52 liters / minute

Here's a great flow rate calculator: http://www.1728.org/flowrate.htm

Find mZPQR.<br> help asap
DENIUS [597]
<h3>Answer: D) 72</h3>

======================================

Work Shown:

Angle PQR = (far arc - near arc)/2

2x+72 = ( (2x+252) - (2x+108) )/2

2x+72 = 144/2

2x+72 = 72

2x = 72-72

2x = 0

x = 0/2

x = 0

-------------

Angle PQR = 2x+72

Angle PQR = 2(0)+72

Angle PQR = 72 degrees
