Question
Deion made a pumpkin pie. After measuring the pie tin, Deion calculated it has an area of 34.1946 square inches. What is the pie tin's circumference?
Solution
To find the circumference of the pie tin, we first need to understand that the area of a circle (which is the shape of the pie tin) is given by the formula A = πr², where A is the area and r is the radius of the circle.
Given that the area A is 34.1946 square inches, we can rearrange the formula to solve for r:
r = sqrt(A/π) = sqrt(34.1946/π) = sqrt(10.8796) = 3.3 inches (approximately)
Now that we have the radius, we can find the circumference using the formula C = 2πr:
C = 2π * 3.3 = 20.7 inches (approximately)
So, the circumference of the pie tin is approximately 20.7 inches.
