Answers
Large size pizaa is better value for money
Step-by-step explanation:
Question is Which pizza is better value for money
Smaller One diameter = 30 cm
Radius = 30/2 = 15 cm
thickness = h cm
Volume = π R² h
= π 15² h
Larger One diameter = 40 cm
Radius = 40/2 = 20 cm
thickness = h cm
Volume = π R² h
= π 30² h
= π (2 * 15)² h
= 2² * π 15² h
= 4 π 15² h
Volume of Larger One = 4 Times Volume of Smaller One
=> Volume of Larger One/Volume of Smaller One = 4/1
Cost of Larger one = 40 Zed
Cost of Smaller one = 30 Zed
=>Cost of Larger one/Cost of Smaller one = 40/30
=> Cost of Larger one/Cost of Smaller one = 4/3
4/1 > 4/3
Volume ratio of larger > Cost Ratio
=> Large size pizaa is better value for money
