Question

What is the ratio of the area of a circle with radius r to the circumstances of a circle

Answer 1

Answer:

$ratio=\frac{r}{2}$

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

$A=\pi r^{2}$

The circumference of the circle is equal to

$C=2\pi r$

To find out the ratio, divide the area by the circumference

$ratio=\frac{A}{C}=\frac{\pi r^2}{2\pi r}$

Simplify

$ratio=\frac{r}{2}$
