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.
