On a test I had recently it had this question:
Let a>0 and b>0 be given constants. Let R be the region in the first quadrant limited by y=ax^2 and y=b. Find the volume of the solid obtained by rotating R about the y-axis.

I know the answer and I can sketch the region properly but I still don't understand the reasoning as to why my professer used a diffrent function to solve than I did.

What I'm asking is people with longer legs can run for longer at a constant speed,

But people with short and more muscles in there legs can run faster but for shorter distances.

People with more muscles in legs, can get a better start or thrust the peole with long legs
Longer Leggers are Marthone Runners

Muscle Short Leggers are Sprinters?
