Answer:
r = 5.848cm, h = 11.696cm
Step-by-step explanation:
Surface area: 
Volume: 
Therefore, the height of a cylinder given its volume would be
, thus:

We now find the derivative of the surface area of the cylinder with respect to its radius and set it equal to 0, solving for the radius:






If
, then the surface area of the cylinder increases
Therefore, the surface area is minimized when the radius is
, making the minimum height
.
In conclusion, the 2nd option is correct.
Answer:
50
Step-by-step explanation:
What I did was 2 divided by 100 = 0.02 Then multiply 0.02 times 500 and you should get 10 then multiply by how many years of interest and you get 50

Y=radical 3
just cancel out the 2 on both sides
