What is the approximate measure, in degrees, of the central angle of the circle whose radius is 15 m and arc length is 10 m?

Respuesta :

Answer:

[tex]38.2\°[/tex]

Step-by-step explanation:

we know that

The circumference of a circle is equal to

[tex]C=2\pi r[/tex]

we have

[tex]r=15\ m[/tex]

substitute

[tex]C=2\pi (15)=30\pi\ m[/tex]

Remember that

[tex]360[/tex] degrees subtends the complete circle of length  [tex]30\pi\ m[/tex]

so

by proportion

Find the approximate measure, in degrees, of the central angle of the circle whose radius is 15 m and arc length is 10 m

so

[tex]\frac{360}{30\pi}=\frac{x}{10}\\ \\x=360*10/(30\pi)\\ \\x=38.2\°[/tex]
