Answer:

a) A = 36π in² ≈ 113.09 in²

b) $0.98 per slice

c) $0.09 per square inch

Step-by-step explanation:

a) area = πr²

r= diameter/2 = 12/2 = 6

A = π(6)²

A = 36π in² ≈ 113.09 in²

b) s = price per slice

s = 9.75 ÷ 10

s = $0.975 ≈ $0.98

c) price per square inch = price ÷ area

= 9.75 ÷ 113.09

= $0.086 ≈ $0.09 per square inch
