Final answer:
A dilation would change both the center and the radius of Maria's circle, while rotation, reflection, and translation would only affect its position or orientation.
Step-by-step explanation:
The transformation that could cause the image of Maria's circle to have a different center and a different radius than the original is dilation. Dilation involves changing the size of a figure while maintaining its shape, which would result in a circle with a different radius. Unlike dilation, a rotation, reflection, or translation would not change the size of the circle; only its position or orientation would be affected.
