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?
area = pi d^2/4 = 3.14159 (144)/4 = 113.1 in^2
12.55 /113.1 = .1109 dollars/in^2
or about 11.1 cents / square inch
i actually need the anwser my self
11 cents
11 cents
11 cents ;)
To find the cost per square inch of the pumpkin pie, we first need to calculate the area of the pie. The area of a circle is calculated using the formula: π * (radius)^2.
Given that the diameter of the pie is 12 inches, we can determine the radius by dividing the diameter by 2. So, the radius (r) is 12 inches / 2 = 6 inches.
Now we can calculate the area (A) of the pie using the formula: A = π * (6 inches)^2.
Since the value of π is approximately 3.14, we can substitute it into the formula: A = 3.14 * (6 inches)^2.
Simplifying the equation gives us: A = 3.14 * 36 square inches, which equals approximately 113.04 square inches.
To find the cost per square inch, we need to divide the cost of the pie by the area of the pie. So, $12.55 / 113.04 square inches ≈ $0.111 per square inch.
Therefore, the cost per square inch of the pumpkin pie is approximately $0.111.
