Question

find the length of the tangent from a point which is 9.1cm away from the centre of the circle ,whose radius is 8.4cm​

Answer 1

Step-by-step explanation:

Let the length of tangent be x cm.

Given:- radius of circle = 8.4 cm.

the distance from centre = 9.1cm.

now, using Pythagoras theorem,

x = √(9.1)^2 - (8.4)^2

x = √82.81 - 70.56

x = √ 12.25

x = 3.5

Hence , length of tangent = 3.5 cm.
