how to find the radian measure of the central angle of a circle of radius that intercepts an arc of length.


Radius r                               Arc Length
1.) 15inches                              18inches

 

2.) 14.5centimeters                  25centimeters

Sagot :

[tex]radian = \frac{arc length}{radius} [/tex]

1) [tex]radian = \frac{18}{15} = \frac{6}{5} = \boxed{1.2 rad}[/tex]

2) [tex]radian = \frac{25}{14.5} = \frac{50}{29} = \boxed{1.72 rad}[/tex]
