Question

1. The length of a tangent from a point A at distance 5 cm from the
centre of the circle is 4 cm. Find the radius of the circle.​

Answer 1

Answer:

5 square - 4 square =9root =3

rad3×2=6

Answer 2

Answer:

Step-by-step explanation:

let x be the radius of the circle

let the tangent be AP

thus , P = 90 (tangent is perpendicular to radius)

therefore by pythagoras theorem =

5²-4² = x²

thus , x =3 cm ( i think u typed the question incorrectly as the length of the tangent should be 5cm)
