Question

PLEASE HELP ME! 8 points!! What is the radius?

Answer 1

Here is the formula:

`(s)/(angle) = (r)/(1)`

s = arc length

r = radius

angle = angle, but in radian form which is what the problem originally gave you so you don't have to do any conversions

so...

`((10\pi )/(3) )/((2\pi )/(3) ) = (?)/(1)`

Then cross multiply and you get...

`(10\pi )/(3) =(2\pi )/(3) x`

Multiply
`(3)/(2\pi )` to both sides to isolate x and you will get...

5 = r

The radius is 5

Hope this helped!
