Question

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

​

Answer 1

Answer:

It means the triangle made by joining radius , tangent and the center of circle will be a right triangle. Hence, the radius of the circle is 5 cm.

Think circle center is O and PT = 13 cm the tangent touching circle at T, OT is the radius and OP= 12 cm the hypotenus.

As angle, PTO is 90 Degree, Triangle PTO is a right angle triangle where OT is the radius and is just Root (13^2 - 12^2) = 5cm

Step-by-step explanation:

So, the answer is 5cm.
