Question

The circle has a circumference of 22pi inches then what would its radius be
* i need radius to find an arc length

Answer 1

Circumference = 2*pi*radius

C = 2pi*r

C/(2pi) = r

r = C/(2pi)

Answer 2

Now plug in C = 22pi and simplify to find r

Answer 3

well 22pi=69.08
would i sq that ?

Answer 4

No need to approximate it, just plug it in and simplify


r = C/(2pi)

r = (22pi)/(2pi)

r = 22/2

r = 11
