Question 990244: You have been asked to design a can shaped like a right circular cylinder with height h and radius r. Given that the can must hold exactly 170 cm^3, what values of h and r will minimise the total surface area (including the top and bottom faces)? Give your answers correct to 2 decimal places as a list [in brackets] of the form: [ h, r ]
for constants h (height), r (radius), in that order.

, , and .

s is for surface area of the can.

v formula gives

Find ds/dr and equate to 0, and solve this for r.

Actually, you are looking for ------Solve this for r.
