PLEASE HELP ME. ANY HELP IS APPRECIATED Circle A has center of (2, 3) and a radius of 5, and circle B has a center of (1, 4) and a radius of 10. What steps will help show that circle A is similar to circle B?

This might be a trivial question.
Similar shapes have the same ratios but not necessarily the same size.
Eg a 3,4,5 triangle is similar to a 6,8,10 triangle.
If this is what the question means by “similar” then surely all circles are similar by definition because C = pi x d in every circle.
