Two circles of radii 5 cm and 2 cm have their centres 3 cm apart. Compare the distance between centres with the difference of radii (5 - 2 = 3 = distance), then state how many common tangents they have.

Question

Accepted Answer

1. Distance between centres (3) equals difference of radii (5-2=3), so the circles touch internally, giving 1 common tangent.

Two circles of radii 5 cm and 2 cm have their centres 3 cm apart.
Compare the distance between centres with the difference of radii (5 - 2 = 3 = distance), then state how many common tangents they have.
