Answer:
[tex]ratio=\frac{r}{2}[/tex]
Step-by-step explanation:
The correct question is
What is the ratio of the area of a circle with radius r to the circumference of a circle
we know that
The area of the circle is equal to
[tex]A=\pi r^{2}[/tex]
The circumference of the circle is equal to
[tex]C=2\pi r[/tex]
To find out the ratio, divide the area by the circumference
[tex]ratio=\frac{A}{C}=\frac{\pi r^2}{2\pi r}[/tex]
Simplify
[tex]ratio=\frac{r}{2}[/tex]
