Let ,
Centre of the circle b = P
AB is chord
N is the centre of the chord .

NB=24.67cm
As N is the midpoint of the chord AB
So ,
\begin{gathered} \text{Length of Chord AB = 2NB} \\ \\ = 2 \times 24.67\end{gathered}
Length of Chord AB = 2NB
=2×24.67
Hence,
\underline \pink{ \underline{\text{ \bf Length of Chord AB = 49.34 cm(approx)}}}
Length of Chord AB = 49.34 cm(approx)
