Two circles of radii 6 cm and 2 cm are such that the distance between their centers is 8 cm. How many common tangents can be drawn?

1. 0
2. 1
3. 2
4. 3

Correct answer: 3

Solution

For two circles, if the distance between centers equals the sum of radii, they touch externally. In that case, there are 3 common tangents: two direct tangents and one transverse tangent.
