A round 12-inch woofer is mounted to the bottom of a rectangular speaker enclosure with an inner width measurement of 12 inches. How far from corner A is the center, O, of the woofer?

To find the distance from corner A to the center of the woofer, we can use basic geometry principles.

Let's draw a sketch of the rectangular speaker enclosure. Label corner A as the starting point and O as the center of the woofer.

In the diagram, we can see that the woofer is mounted at point X, which is in the center of the enclosure. We need to find the distance from corner A to point X.

Since the inner width of the enclosure is given as 12 inches, we know that the distance from corner A to point X will be half the width of the enclosure. Therefore, to find the distance, we'll divide the width measurement by 2.

So, the distance from corner A to the center O of the woofer is:

Distance = Width / 2
Distance = 12 inches / 2
Distance = 6 inches

Hence, the distance from corner A to the center O of the woofer is 6 inches.
