Answer:

r=5.42cm

h=10.83cm

Step-by-step explanation:

Hello!

To solve this problem please use the following steps, the complete procedure is attached.

1. Raise the equation for the volume of a cylinder and solve for the height (H)

2. Use the equation for the surface area of ​​a cylinder, and replace the height using the equation found in step 1.

3. Derive the equation with respect to the radius and equal it to zero, then solve for the radius of the cylinder. Remember that the objective is to find that with the minimum surface area, the required volume is generated.

4. Once the radius is found, find the height with the equation from step 1
