Answer:
A.
Step-by-step explanation:
Recall that circumference is given by:
[tex]C=2\pi r[/tex]
We know that the circumference is 8π inches. Thus, we can substitute 8π for C:
[tex]8\pi =2\pi r[/tex]
To solve for r, the radius, we can divide both sides by 2π. Hence:
[tex]\displaystyle r = \frac{8\pi}{2\pi}=4[/tex]
Therefore, the radius is four inches.
Our answer is A.
