If we expand (3x^2 - 1)^4 we get, (3x^2 - 1)^4 = 81x^8 - 108x^6 + 54x^4 - 12x^2 + 1 If we derive (3x^2 - 1)^4 we get, (via chain rule) 24x(3x^2...

A solid is formed by attaching a hemisphere to each end of a cylinder. If the total volume is to be 120cm3, find the radius (in cm) of the cylinder that produces the minimum surface area. Express...
