Answer:

Step-by-step explanation:

To solve this, we first need the area of the square, then subtract from it the area of the circle. Since our instructions tell us to round to the nearest hundredth, we will use 3.1415 for pi. First the square:

A = s * s so

A = 15 * 15 and

A = 225; next the circle:

A = 3.1415 * 7.5*7.5 (the area of a circle is pi times the radius squared. The radius is half of the diameter which is 15, so r = 7.5) so

A = 176.709

Subtracting the area of the circle from the area of the square:

225 - 176.709 = 48.29 ft squared.
