Answer:
[tex]\large\boxed{d=\dfrac{C}{\pi}}[/tex]
Step-by-step explanation:
It's the formula of a circumference:
[tex]C=\pi d[/tex]
d - diameter
Solve for d:
[tex]\pi d=C[/tex] divide both sides by π
[tex]d=\dfrac{C}{\pi}[/tex]
Answer:
he is right. you need to divide both sides by pie which is 3.14
