Answer:
3317.5 square inches
Explanation:
The missing question is: Determine the surface area of the drum.
Data
- radius of the drum, r = 12 inches
 
- height of the drum, h = 32 inches
 
The drums are cylinders. 
surface area of a cylinder = 2*π*r*h+ 2*π*r² = 2*π*12*32+ 2*π*12² = 3317.5 square inches
