The equation for the volume of a cylinder is pir^2h or 3.14*radius squared* height.
We can switch the equation around to find r^2=v/3.14*h
Now insert the known values.
R^2=1500/3.14*15
Solve
R^2=1500/47.1
R^2=31.8
R=5.6
Hope this helps!
Using sampling concepts, it is found that the sample would not support a valid inference, as both alphabetized and non-alphabetized students should be sampled.
<h3>What is sampling?</h3>
It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.
The school has both alphabetized and non-alphabetized students, and both groups should be sampled for a valid inference to be made. Since only alphabetized students are sampled, the sample would not support a valid inference.

Answer:
y=0.79x+27
Step-by-step explanation:
y is total cost and 0.79is per mile cost last is 27
so is y=0.79x+27
