Answer:
a) 80
b) 56
Step-by-step explanation:
a) Calculate the volume of the the cup using volume of cylinder equation:
Where V = Volume, r=radius, and h=height. Your answer should be in cubic inches ().
You're given diameter, so use equation to find radius.
Substituting these equations will give you:
However, the given volume of the sink is 3000, meaning that you should modify your results to match this value. Do not substitute
for 3.14..., leave it as a symbolic value. Your final V of the cup should = 37.5
Divide the volume of the sink by the volume of the cup. This number will be the amount of cups needed to empty it. In equation form: # of cups.
Note the the will cancel each other out, so there's not need to factor that in.
b) Repeat the steps above with the new d (diameter) value.
