### Explanatory Answer

Circle K has twice the radius of circle M.

Let’s call the radius of Circle M as r.
Radius of Circle K = 2r

Area of Circle M = π r2
Area of Circle K = π (2r)2 = 4 π r2.

Area of Circle K is 4 times the area of Circle M.

Therefore, ratio of the area of Circle M and the area of Circle K is 1 : 4

The question is "What is the ratio of the area of Circle M and the area of Circle K?"

##### Hence, the answer is 1:4
