A right circular cylindrical metallic rod is 15 inches tall. The radius of the base is 2 inches. What is the surface area of the metallic rod in terms of pie?

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
