Answer 1

the length of the radius is 12 CM.

hope this helps you and mark me as the brain list.

Answer 2

PQ is a tangent and PAB is a secant

PQ² = PA × PB. ( tangent secant segments theorem )
5² = 1 × PB
25 - 1 = PB
PB = 24


Now,
AB = PB - PA
AB = 24- 1
AB = 23


Now,
radius = OA = ½× AB
radius = OA = ½ ×23
radius = OA = 11.5 cm
