Answer:
[tex]\dfrac{c}{28}=\pi[/tex]
Step-by-step explanation:
The circumference [tex]c[/tex] of circle of radius [tex]r[/tex] is given by
[tex]c=2\pi r[/tex],
and the diameter [tex]d[/tex] is 2 times the radius:
[tex]d=2r[/tex].
Therefore, the ratio of the circumference to the diameters is
[tex]\dfrac{c}{d}=\dfrac{2\pi r}{2r}[/tex]
[tex]\dfrac{c}{d}=\pi[/tex].
Putting in [tex]d= 2r =28[/tex], we get
[tex]\boxed{ \dfrac{c}{28}=\pi}[/tex]
