A circle has radius of 6 cm, and there is a point situated 10 cm away from the center of the circle. A tangent is drawn from this point to touch the circle. Calculate the length of the tangent segment.
Show answer & explanation
Correct answer: B
Explanation
Given:
Radius of the circle = 6 cm
Distance of point P from the center = 10 cm
Formula:
Length of the tangent = √(OP² − r²)
PT = √(10² − 6²)
= √(100 − 36)
= √64
= 8 cm
