Find the length of tangent drawn to a circle of radius 6 cm from a point at a distance of 10 cm from the center of the circle?
Answer: 8 cm
Explanation
Let's denote the length of the tangent as l.
We know that the radius is perpendicular to the tangent at the point of contact.
Using the Pythagorean theorem:
l² = 10² - 6²
= 100 - 36
= 64
l = √64
= 8 cm
