    1. Given:
      – Length of tangent = 24 cm,
      – Distance from Q to center = 25 cm.

      Using Pythagoras theorem:
      25² = 24² + r².

      Simplify:
      625 = 576 + r².

      Solve for r:
      r² = 49 ⇒ r = 7 cm.
      This question related to Chapter 10 Mathematics Class 10th NCERT. From the Chapter 10 Circle. Give answer according to your understanding.
