If point Q is 7 cm away from the center of a circle and the radius of the circle is 4 cm, then how many tangents can be formed from point Q?
- 2
- 3
- 1
- None of these
Explanation
Rule:
If distance < radius → point inside → 0 tangent
If distance = radius → point on circle → 1 tangent
If distance > radius → point outside → 2 tangents
Here: Distance of Q = 7 cm, Radius = 4 cm
7 > 4, so Q is outside the circle, so 2 tangents can be drawn.
