Answer 2

To find the area of the cloth cut from the square, we need to subtract the area of the circle from the area of the square.

The area of the square is given by: 38 inches x 38 inches = 1444 square inches.

The formula for the area of a circle is: π x r^2, where r is the radius of the circle.

In this case, the radius of the circle is half of the side of the square, which is 38/2 = 19 inches.

Substituting into the formula, the area of the circle is: 3.14 x 19^2 = 3.14 x 361 = 1135.54 square inches.

Finally, to find the area of the cloth cut from the square, we subtract the area of the circle from the area of the square: 1444 - 1135.54 = 308.46 square inches.

Therefore, the correct answer is 308.46 in2.

Answer 3

I apologize for the confusion. The correct answer is indeed 1,133.54 in2.
