Answer:
a rise of 20 degrees
Step-by-step explanation:
since it started at -2 degrees, you have to add enough to get out of the negatives. 
-2 + 2= 0, then 0+18 to get to the 18°
-2 + 20 = 18

Answer:



Step-by-step explanation:
r = Radius
h = Height
Volume of cylinder = 

Surface area is given by

Differentiating with respect to radius we get

Equating with zero we get


So, the value of the function is minimum at 

So, the radius and height which would minimize the surface area is 1.05 feet and 2.12 feet respectively.
Surface area

The minimum surface area is  .
