Answer:
B I think..................................
Well the radian is the measure of the radius
this line measure is then ligned up to the circumference
mearuse of 1 raidan is always equal to the measure of the radius therfor the true statements are
ratio of arc legnth to r is always equal to 1
I'm not sure what 'if the measure of is'
but I think the answer is
if the measure of is 1 radis, than the arc legnth is r since r reaprensents radius
so first and third choice are correct
3.14*r^2
Hope it helps you figure them out
