Respuesta :

C is the correct answer.

Answer:

Option C.

Step-by-step explanation:

The given expression is c = 8πab

We have to solve this for the value of a

Dividing the expression by 8πb on both the sides.

[tex]\frac{c}{8\pi b}=\frac{8\pi a b}{8\pi b}[/tex]

[tex]a=\frac{c}{8\pi b}[/tex]

Therefore, Option C. will be the answer.
