# Chord MN

Chord MN of circle has distance from the center circle S 120 cm.
Angle MSN is 64°. Determine the radius of the circle.

Result

r =  141.5 cm

#### Solution:

$r = \dfrac{ 120}{ \cos(\dfrac{ 64 ^\circ }{2}) } = 141.5 \ \text{cm}$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
