The diameter of the first circle is 2 times the radius of the second circle.

The diameter of the first circle is 2 times the radius of the second circle. Is it possible to place these circles so that one of them fits completely into the other?

Since, according to the condition of the problem, the diameter of the first circle is twice the radius of the second circle, it turns out that the diameters of the two circles are equal (by definition, d = 2r), therefore, these are two identical circles and neither of them fits completely into the other.
