Question

the pair of tangents ab and a cube drawn from an external point to a circle with Centre O are perpendicular to each other and the length of each tangent Spice and then the radius of a circle is how many ​

Answer 1

Answer:

external point to a circle with Centre O are perpendicular to each other and the length of each tangent Spice and then the radius of a circle is how many

Step-by-step explanation:

external point to a circle with Centre O are perpendexternal point to a circle with Centre O are perpendicular to each other and the length of each tangent Spice and then the radius of a circle is how many external point to a circle with Centre O are perpendicular to each other and the length of each tangent Spice and then the radius of a circle is how many icular to each other and the length of each tangent Spice and then the radius of a circle is how many

Answer 2

Join OA.

Triangles OPA and OQA are congruent.

⇒∠PAO=∠QAO=45°

Tangent and radius are perpendicular at the point of contact.

∠OPA=90°

⇒∠OAP=∠AOP=45°

⇒OP=AP=4cm

So the radius of the circle is 4 cm.
