Geometry

Question Analysis:
This question tests surface area based on diameter and real-life object (soda can).
The main focus is using lateral area with radius = diameter ÷ 2.

Key Concept Explanation:
Lateral area = 2πrh.
Use r = 6.5 ÷ 2 = 3.25 cm

Step-by-Step Solution:
r = 3.25, h = 12.5
2πrh = 2π × 3.25 × 12.5
= 81.25π cm²

Common Mistakes:
Using diameter i...
