To find the area of a circle, we use the formula A = πr^2, where A represents the area and r represents the radius.
Given that the radius of the circle is 6 inches, we can substitute this value into the formula to find the area:
A = 3.14 * 6^2
A = 3.14 * 36
A ≈ 113.04 sq in
Therefore, the area of the circle is approximately 113.04 sq in.
The correct answer is D. 113.04 sq in.

A. 72.55
B. 42.68
C. 12.22
D 27.45
To find out how much change Sinead received, we need to add up the cost of the shirts and shoes and subtract it from the amount of money she paid with.
The cost of the shirts can be calculated by multiplying the price per shirt by the number of shirts: 2 * 15.23 = 30.46.
The total cost of the shirts and shoes is the sum of the cost of the shirts and the cost of the shoes: 30.46 + 42.09 = 72.55.
To find out how much change Sinead received, we subtract the total cost from the amount of money she paid with: 100 - 72.55 = 27.45.
Therefore, Sinead received $27.45 in change.
The correct answer is D. 27.45.
