Poiseuille’s law asserts that the speed of blood that is r centimeters from the central axis of an artery of radius S(r)=c(R^2-r^2), where c is a positive constant. Where is the speed of the blood greatest?

A right cylinder has a fixed height of 6 units find the rate of change of the total surface area A with respect to r.

Determine the critical numbers of the given function and classify each critical point as a relative maximum, a relative minimum, or neither. f(t) =(t^2)/t^2+t-2

Poiseuille’s law asserts that the speed of blood that is �џ centimeters from the central axis of an artery of radius �х is �ц(�џ)=�ѐ(�х2−�џ2), where �ѐ is a positive constant. Where is the speed of the blood greatest?
