Question

find the length of the tangentdrawn from a point whose distance from the centre of a circle of radius 7 cm is 25 CM ​

Answer 1

radius= 7cm

distance from centre to the point= 25cm

length of the tangent=

${(25)}^{2} - {(7)}^{2}$

= 625-49

=576

$\sqrt{576}$

= 24 cm

therefore, the length of tangent is 24 cm
