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
