A 7-inch apple pie sells for $4. What is its cost per square inch (in Sq.?
A = pi * r^2
A = 3.14 * 3.5^2
A = 38.465 sq. in.
4 / 38.465 = 0.1048 = $0.10 per sq. in.
Well, let's take a bite out of this math problem, shall we? To find the cost per square inch, we need to divide the price of the pie by its area. Since the pie is 7 inches in diameter, we can calculate its radius as 7/2 = 3.5 inches.
The area of a circle is πr², so the area of the apple pie is π(3.5)² = 38.48 square inches (approximately).
Now, let's divide the cost of the pie ($4) by its area.
$4 / 38.48 sq. inches ≈ $0.10 (rounded to two decimal places)
So, the cost per square inch of this apple pie is approximately 10 cents. In other words, you're paying a dime for a delicious slice of pi!
To find the cost per square inch of a 7-inch apple pie, you need to calculate the area of the pie first. The area of a circular pie can be found using the formula A = πr^2, where A is the area and r is the radius.
Since the pie's diameter is 7 inches, its radius is half of that, which is 3.5 inches.
A = π(3.5)^2
A = π(12.25)
A ≈ 38.48 square inches
Now, to find the cost per square inch, you divide the total cost by the area.
Cost per square inch = Cost of the pie / Area of the pie
Cost per square inch = $4 / 38.48 sq. inches
Approximately, the cost per square inch of the 7-inch apple pie is $0.10 (10 cents).
To find the cost per square inch of the apple pie, we need to divide the total cost of the pie by its area.
First, let's calculate the area of the apple pie. The pie is circular, so we can use the formula for the area of a circle: A = π * r^2, where A represents the area and r represents the radius.
Given that the diameter of the apple pie is 7 inches, we can find the radius by dividing the diameter by 2: r = 7/2 = 3.5 inches.
Now, we can calculate the area of the apple pie using the formula: A = π * 3.5^2 ≈ 38.48 square inches.
Next, let's determine the cost per square inch. We divide the total cost of the pie ($4) by its area (38.48 square inches).
Cost per square inch = Total cost / Area
Cost per square inch = $4 / 38.48 square inches
Cost per square inch ≈ $0.104 or approximately 10.4 cents
Therefore, the cost per square inch (in sq. inch) of the 7-inch apple pie is approximately 10.4 cents.
