Pizza 1: price ÷ area
price ÷ (π × (d ÷ 2) to the power of 2)
12.00 ÷ (π × (12 ÷ 2) to the power of 2) = 0.1061 per sq in
Pizza 2: price ÷ area
price ÷ (π × (d ÷ 2) to the power of 2)
18.00 ÷ (π × (16 ÷ 2) to the power of 2) = 0.08952 per sq in
The lowest price per area is the better deal
best = lowest price per area
Pizza 1: 0.1061 per sq in; Pizza 2: 0.08952 per sq in = Pizza 2 (16 in)
