Question

the length of tangent to a circle which is 13cm distance from the centre of the circle is 12cm. find the radius of the circle.​

Answer 1

Answer: 5 cm

Step-by-step explanation:

Hi friend!!

The tangent, the distance of the tangent from the center of the circle and the radius forms a right angled triangle.

So, by Pythagorean triplet, 12,13 and 5 form a right angled triangle.

Hence, the radius is 5 cm.

Hope it helps!!!

Answer 2

Step-by-step explanation:

By using Pythagoras theorem

(radius)sq.=(length of tangent)sq.-(distance from the centre) sq.

=(13)sq.-(12)sq.

=169-144

=25

(radius)sq.=25

radius. =√25

=5

Hence the radius is 5 CM.........
