Step-by-step explanation:
R = C/(2*Pi).
So, in order to find the radius from the circumference, you use the formula R = C/(2*Pi). In other words, just divide the circumference by 2 times pi.
4 divide 4/9
4 times 9/4
= 9
Narrowing it down it's either a or c because the other 2 choices open downward (negative a).
