I'm having trouble with the following problem from my homework for a Calc. II course:
Any help would be really appreciated, thanks.The velocity v of the flow of blood at a distance r from the central axis of an artery of radius R is,
where k is the constant of proportionality. Find the average rate of flow of blood along a radius of the artery. (Use 0 and R as the limits of integration.)
EDIT: I should probably clarify: I know how to use integration in order to find the average value of a function over a range. It's integrating the function that I'm stuck on.
