All circles are similar because all circle have same shape.
However Two circles are congruent , if and only if their radii are congruent.
In our question we are asked when are all circles similar given if their radii are congruent.
So we can say this statement is false because no matter the radii are congruent or not , two or more circles are always similar because of their same shape no matter what the measure of their radii is. Only if we are asked when they are congruent, we will consider the radii part.
Answer is false.

Step-by-step explanation:

8x-15=8x+15
-15=15
the fees in 1997 was $3088
fees in 2000 was $3292
average rate of increase= (3292-3088)/(2000-1997) = 204/3=68
so average rate of increase is $68 per year
