- A5 cm
- B10 cm
- C4 cm
- D6.5 cm
Step-by-Step Solution
, so cm. is a diameter of length 18 − 8 = 10 cm, so the radius is 5 cm.
Answer: A) 5 cm
From a point P outside a circle, the tangent PT is 12 cm long. A line from P through the centre meets the circle first at A and then at B, with PA = 8 cm. Find the radius.
