Industrial chemicals are stored in 55-gallon drums. The radius of the drum is 12 inches, and the height is 32 inches.

3317.5 square inches

Step-by-step 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
