2. A manufacturer wants to make a cylindrical can to hold 200cm 3 of pea and ham soup. Find the dimensions such that the surface area is as small as possible. Surface area = 2πr 2 + 2πrh Need to eliminate one variable V = 200 So 200 = πr 2 x h Substitute into S.A. formula Surface area (A)= More resources available from: free-online-calculator.netfree-online-calculator.net
