The marketing manager of a soft drink company wants to design a can with a height that is four times the radius of the can. a) express the volume of the can as a function of the radius, r b) explain the volume of the can as function of the height, h

Volume of a cylindrical can  = pi r^2 h
We are given that  h = 4r ,  so substituting for h in the above formula:-
Volume = pi * r^2 * 4r  = 4pir^3 <  the answer to Part a.

h = 4r  so r = h/4
Substituting for r:-
Volume = pi * (h/4)^2 * h = pi h^3/16 < Answer to part b.

0.69 yards

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
