Answer: Option D
[tex]\displaystyle d=\frac{C}{\pi}[/tex]
Step-by-step explanation:
To solve the formula for d, we will isolate the d variable.
Given:
C = πd
Divide both sides of the equation by π:
[tex]\displaystyle\frac{C}{\pi}=\frac{\pi d}{\pi}[/tex], [tex]\displaystyle\frac{C}{\pi}=d[/tex]
Reflexive property
[tex]\displaystyle d=\frac{C}{\pi}[/tex]
