Answer:
Step-by-step explanation:
let r be the radius of the cylinder and h the height:
The surface are as a function of the radius and the first derivative is calculated as;
Hence, the least surface area is achieved when the height and radius of the cylinder is equal,
The answer for that is 23/16
The answer is to 2+2 is equal to 4
