Answer:
The ratio of the circumference to the diameter of a circle is equal to [tex]\pi[/tex]
The equation is [tex]\frac{C}{30}=\pi[/tex]
Step-by-step explanation:
we know that
The circumference of a circle is equal to
[tex]C=\pi D[/tex]
we have
[tex]D=2r=2(15)=30\ units[/tex] ----> the diameter is two times the radius
so
[tex]C=30\pi\ units[/tex]
so
[tex]\frac{C}{30}=\pi[/tex]
The ratio of the circumference to the diameter of a circle is equal to
[tex]ratio=\frac{30\pi}{30}[/tex]
simplify
[tex]ratio=\pi[/tex]
