Technical Notes

• Area calculations use the formula: A = π(d/2)²
• Cost per square inch = Total Price / Pizza Area
• Recommendations include a safety margin for varied appetites
• Calculations assume standard crust thickness and slice sizes

Remember: These calculations provide estimates. Actual portions may vary based on factors like appetite, other available food, and specific pizza styles.
