Answer:

<h2>MN = 9.1 cm</h2>

Step-by-step explanation:

If MN is tangent of a circle then the angle M is a right angle.

We have a dimeter of acircle d = 8 cm.

Therefore the radius CM = 8 cm : 2 = 4cm.

In a right triangle CMN use the Pythagorean theorem:

CM^2+MN^2=CN^2

Substitute CM = 4cm and CN = 9.9 cm:

4^2+MN^2=9.9^2

16+MN^2=98.01          <em>subtract 16 from both sides</em>

MN^2=82.01\to MN=\sqrt{82.1}\\\\MN\approx9.1
