In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 270 degrees.



What is the length of the arc?


6.28 ft

​ 9.42 ​ ft

​ 18.84 ​ ft

​ 28.26 ​ ft

Respuesta :

Answer: 28.26 ​ ft

Step-by-step explanation:

The formula to calculate the length of arc [tex]l[/tex] is:

[tex]l=r \theta[/tex]

Where:

[tex]r=6 ft[/tex] is the radius of the circle

[tex]\theta=270\° \frac{\pi}{180\°}=\frac{3}{2} \pi=4.71 rad[/tex] is the angle in radians

[tex]l=(6 ft)(4.71 rad)[/tex]

[tex]l=28.26 ft[/tex] This is the length of the arc
