Answer: Surface area = 68π inches²

Step-by-step explanation:

The formula for determining the total surface area of the circular cylindrical metallic rod is expressed as

Total surface area = 2πr² + 2πrh

Where

r represents the radius of the cylindrical rod.

h represents the height of the cylindrical rod.

π is a constant whose value is 3.14

From the information given,

Radius = 2 inches

Height = 15 inches

Therefore,

Surface area = (2 × π × 2²) + 2 × π × 2 × 15) = 8π + 60π

Surface area = 68π inches²
