In a circle of radius 30 inches, a central angle of 35 will intersect the circle forming an arc of length _____. A. 18.33 feet B. 87.5 inches C. 18.33 inches D. 1.17 feet

Respuesta :

I believe its c. If I am wrong just tell me

Answer:

Option C. [tex]18.33\ inches[/tex]

Step-by-step explanation:

we know that

The circumference of a circle is equal to

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

In this problem we have

[tex]r=30\ in[/tex]

substitute

[tex]C=2\pi (30)=60\pi\ in[/tex]

Remember that

[tex]360\°[/tex] subtends the complete arc of length of [tex]60\pi\ in[/tex]

so

by proportion

Find the arc length by an angle measuring [tex]35\°[/tex]

[tex]\frac{360}{60\pi }=\frac{35}{x}\\ \\x=60\pi *35/360\\ \\x=18.33\ in[/tex]
