Question

what is the ratio of radius of circle to its diameter
​

Answer 1

Answer:

$\frac{1}{2}$

Step-by-step explanation:

Let diameter =d

Then radius =r=d/2

Ratio =

$\frac{radius}{diameter}$

$= \frac{ \frac{d}{2} }{d} = \frac{1}{2}$

Answer 2

Answer:

1. Radius = r
2. Diameter = 2 x r = 2r

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

$= \frac{1}{2}$
