Troy drew the diagram below. The inner circle has a radius of 2 units, and the outer circle has a radius of 5 units. Troy says the 2 circles are similar. Which statement best explains whether Troy is correct and why? A)he is correct because the inner circle is a dilation of the outer circle B) he is correct because the inner circle has the same center as the outer circle C) he is not correct because the inner circles radius is less that the outer circles radius D) he is not correct because the inner circles radius is not half of the outer circles radius
