Geometry

Question Analysis:
This question tests unit conversion and surface area calculation.
The main focus is on maintaining consistent units throughout the calculation.

Key Concept Explanation:
Total Surface Area (TSA) formula requires consistent units:
TSA = 2πr(h + r)
All measurements must be in the same unit before calculating.

Step-by-Step Solution:
Convert radius to meters: 50 cm = 0.5 m
Height is already 2 m
Apply TSA formula: 2π × 0.5 × (2 + 0.5)
Calculate parentheses: 2 + 0.5 = 2.5
Multiply: 2 × 0.5 × 2.5 = 2.5
Final answer: 2.5π m²
