Question

a pumpkin pie costs $12.55 at a bakery. if the pie has a diameter of 12 inch. what is the cost per square inch of the pie?

Answer 1

Diameter of the pie = 12 inch
radius = 12/2 = 6 inch
area of the pie = 6*22/7 = 18.86 sq. inch which cost $12.55
so, cost per sq. inch = 12.55/18.86 = $0.67
