Hi Tyler, the surface area is given by: S = π * d * l, where d is the diameter and l is the length. It is necessary to change all measurements into one unit.

Working with meters:

Calculating diameter of pipe in meters:

Convert centimeters to millimeters:

2.54 * 10 = 25.4 millimeters

Diameter of pipe in millimeters:

2 * 2.3 + 25.4 = 30 millimeters

Diameter of pipe in meters:

30 / 1000 = .03 meters

Surface area of pipe:

S = π * d * l

S = π * .03 * 32

S ≈ 3.02 meters squared
