Formula
Compute areaA = π × diameterA² ÷ 4, areaB = π × diameterB² ÷ 4, costPerAreaA = priceA ÷ areaA, and costPerAreaB = priceB ÷ areaB; the lower unit cost is the better value.
Worked example
Worked example: Inputs: Pizza A diameter: 12 in; Price of Pizza A: 12; Pizza B diameter: 16 in; Price of Pizza B: 18. Outputs: Pizza A area: 113.0973355292 in²; Pizza B area: 201.0619298297 in²; Cost of Pizza A per square inch: 0.1061032954; Cost of Pizza B per square inch: 0.0895246555; Lower cost per area: Pizza B.
