The top and bottom of the cylinder's area is found via Pi*r^{2 }the lateral surface if found 2*pi*h

Volume = pi* radius^{2}* h

I am only given volume, = 500cm^{3 }Also for each square cm of the top and bottom its 10 cents to make, and for the lateral surface its 7 cents to make.

I don't know where to make the connection with all the information to formulate a formula for r to cost; C(r)=
