Question

If radius of a circle is 3cm and tangent is drawn from an external point is 4cm .Find the distance from centre of circle to external point?​

Answer 1

The answer is 5 cm.
Hope this helps :)

Answer 2

Answer:the distance is 5cm

Step-by-step explanation:

Radius, r=3cm

Tangent=4cm

This makes a triangle

Name the triangle OPA

We have to find the hypotenuse

Using Pythagoras theorem

OP^2= OA^2+AP^2

= 3^2+4^2

= 9+16

OP^2=25

OP= root 25

OP= 5cm

Therefore, the distance from the center of a circle to an eternal point is 5cm
