Area od pizza, A = Pi*Diameter^2/4
A1 = Pi*8^2/4 = 50.27 in^2
A2 = Pi*10^2/4 = 78.54 in^2
A3 = Pi*12^2/4 = 113.10 in^2
Cost (C) per sq. in;
C1 = 50.27/9 = $5.59
C2 = 78.54/12 = $6.55
C3 = 113.10/18 = $6.28
The best buy is the first pizza with 8 in diameter as it costs the least per sq. inch.

Answer:
(a-b)^3 = 
Step-by-step explanation:
(a-b)^3 = (a-b)(a-b)(a-b)
According to the perfect cube formula (a-b)^3 = 
And there you have it! The perfect cube formula already solved your equation!
