A circle has an arc of length 24π that is intercepted by a central angle of 80°. What is the radius of the circle?

Respuesta :

I got radius= 54
arc/2pi r = degrees/360
then fill in what you know: 24pi/2pi r = 80/360
Now cross multiply and you get: 8640pi = 160pi r
Now divide both sides by 160pi and you get: 54= r

The radius of the circle will be 54.

Given,

The length of the arc is 24[tex]\pi[/tex].

The angle made by that arc is 80°.

We have to calculate the radius of the circle.

We know that,

[tex]\rm Angle=\dfrac{Arc}{Radius} \\[/tex]

So,

[tex]80^\circ=\dfrac{24\pi }{\rm Radius}[/tex]

Since [tex]\pi[/tex] is equivalent to 180°.

[tex]\rm Radius=\dfrac{24\times 180^\circ}{80^\circ}[/tex]

[tex]\rm Radius =54[/tex]

Hence the radius of the circle is 54.
