Question 4(Multiple Choice Worth 2 points) (Areas of Circles MC) A bakery sells apple pies for $9.15. If the pie has a diameter of 6 inches, what is the approximate cost per square inch of the apple pie? Round to the nearest hundredth. $1.30 $0.64 $0.32 $0.08

Answer 1

$0.32

Explanation:

First calculate the area of the circle using the formula area = pi x the radius squared. The radius is half the diameter (6) so the radius is 3.

Area of the circle = πr²

area of the circle = π x 3²

area of the circle = 28.27 inches²

the cost of the total pie is $9.15, so if you divide it evenly between the number of square inches you will find the cost per square inch

cost per square inch = cost of whole pie ÷ square inches in whole pie

cost per square inch = 9.15 ÷ 28.27

cost per square inch = 0.32

Therefore the cost per square inch of apple pie is $0.32
