Answer:
Length of BP is 11.2 cm.
Step-by-step explanation:
Given : Two concentric circle with center O are of radii 6 cm and 3 cm. From an external point P, tangents PA and PB are drawn to these circle as shown in the figure. If AP = 10 cm.
To find: Length of BP
Solution : There are two concentric circles
AO = 6 cm (larger circle)
BO = 3 cm (smaller circle)
PA and PB are tangents on the circle i.e, ∠OAP = ∠OBP = 90°
Applying Pythagoras theorem, In larger circle
Now, Applying Pythagoras theorem, In smaller circle
Therefore, Length of BP is 11.2 cm.
