The number of tangents that can be drawn to two non-intersecting circles :

4
3
2
13

Correct Answer: 4

Explanation:

We know that when two circle neither touch nor intersect and one lies outside the other, then 4 common tangents can be drawn.
For 4 common tangents , we get
∴ r₁ + r₂ < c₁c₂
Hence ,The number of tangents = 4
