Geometry

Question Analysis:
This question uses practical context (a fuel tank).
The main focus is on using metric units directly in the area formula.

Key Concept Explanation:
Total surface area = 2πr² + 2πrh

Step-by-Step Solution:
r = 0.4 m, h = 1.5 m
2πr² = 2π × 0.16 = 0.32π
2πrh = 2π × 0.4 × 1.5 = 1.2π
Total = 0.32π + 1.2π = 1.52π m²
