Question

Calculate the length of tangent from a point 15cm away from the center of circle of radius 9cm.​

Answer 1

Answer:

Length of tangent = x

Radius =9cm

Distance to the tangent from contre = 15cm.

From the figure :-

(Distance from the centre)²=radius²+length of tangent²

15²-9²=length of tangent²

225-81=length of tangent ²

Length of tangent =√144=12cm .

Therefore,The length of from a point 15cm away from the centre of circle of radius 9cm is 12cm
