I don't have the figure — can you upload it or describe how L, P, and Q are positioned? With only "L is the center" and "PQ = 30" there are multiple possibilities.
Two common cases:
- If PQ is a diameter (i.e. the chord passes through the center L), then PL = PQ/2 = 30/2 = 15 cm.
- In the general case, let d be the distance from L to the midpoint of PQ. Then half the chord is 15 and the radius r = PL = sqrt(15^2 + d^2). So you need d (the perpendicular distance from the center to the chord) to get PL.
Send the figure or state whether PQ passes through L (or give d) and I'll give the exact numeric answer.
