Answer:
The cost per square inch of the pie is $0.111 or 11 cents
Explanation:
The shape of a pie is circular.
The area of a circle (pie) = πr²
From the question ,
Diameter = 12 inches
Radius = Diameter/2
Radius = 12 inches/2
Radius = 6 inches.
Hence, the area of the pie = π × 6²
= 113.09733553 square inches
A pie costs $12.55
The cost per square inches of the pie is calculated as:
113.09733553 square inches = $12.55
1 square inch = $x
Cross Multiply
113.09733553x = $12.55
x = $12.55/113.09733553
x = $0.1109663631
Approximately
x = $0.111
Therefore, the cost per square inch of the pie is $0.111 or 11 cents
