Geometry

Question Analysis:
This question tests understanding of total surface area and whether material is sufficient.
The main focus is on comparing actual surface area of a cylinder to a fixed available sheet.

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

Step-by-Step Solution:
r = 5, h = 5
2πr² = 2π × 25 = 50π
2πrh = 2π × 5 × 5 = 50π
Total = 50π + 50π = 100π cm²
This gives 100π cm² — far less than 250π
So the sheet is more than enough
