Answer:

Step-by-step explanation:

If this was an entire circle, the area could be found by using

Area = pi * r^2 where r = 9

To take the central angle into account, use this formula

Area = 120/360  * pi * r^2

Area = 1/3 * pi * 9^2

Area = 27 pi

area  = 84.78 cm^2  which isn't there.

DochEvi [55]

Answer:

11 hours

Step-by-step explanation:

I came up with this answer by dividing the IV infiltrate in the bag by the rate. This gave the completion time.

Volume of IV infiltrate = 330ML

Rate at which it was running = 30 ML/hour

The IV completion time = volume/rate

= 330 ML/30 ML

= 11 hours

Therefore the IV completion time is 11 hours.
