Question

The length of a tangent from a point A at distance 5cm from center of circle is 4cm find radius of circle. I need the diagram as well as the solution... Can anyone help me?

Answer 1

Answer:

3cm

Step-by-step explanation:

Radius is always perpendicular to the tangent so apply pythagorous theorem.

Answer 2

Answer:

let's centre Be O and AB be the tangent.

then angle OAB = 90

by Pythagoras theorem

OA2 = AB2 + BO2

=52=42+BO2

= BO2 is equal to 25 - 16

bo2 is equal to 9

bo =3

therefore the radius of the circle is 3

I hope this answer is true
