Question: What is the length of the tangent from a point 10 units away from the center of a circle with a radius of 6 units?

Options:

1. 8
2. 10
3. 12
4. 14

Correct Answer: 8

Solution:

Using the tangent length formula: length = √(distance from center² - radius²) = √(10² - 6²) = √(100 - 36) = √64 = 8.
