For items \( 39-47 \) refer to the figure on the right. \( \odot Q \) has a radius of 7 units and \( \odot T \) has a radius of 4 units. value. 39. \( P S=14 \) Units 40. \( R U=8 \) units

When working with circles, it’s essential to remember that the radius is the distance from the center to any point on the circle. In this case, the \( \odot Q \) with a radius of 7 units has a diameter of 14 units, and similarly, the \( \odot T \) with a radius of 4 units has a diameter of 8 units. Understanding these concepts lays the foundation for solving various geometric problems involving circles. Imagining circles in real-world contexts can help to visualize and apply these mathematical principles. For example, if you picture \( \odot Q \) as a large pizza and \( \odot T \) as a smaller one, you can intuitively grasp the differences in size. This can also come in handy when trying to determine how many smaller pizzas fit on a table next to the larger one!
