Question

The circumference of a circle is 36 cm.
What is the radius of the circle?

Answer 1

The radius is 6 cm rounded

Explanation:

`C` stands for circumference

`r` stands for radius

here's the formula to find the radius:
`r=(C)/(2\pi )`

`r=(36)/(6.283)`

`r=5.729`

Hope this helps

Answer 2

r = 18/pi or approximately 5.732484076 cm

Explanation:

The circumference of a circle is given by

C = 2 * pi *r

36 = 2*pi*r

Divide each side by 2 pi

36 / (2pi) = 2pi r/ (2pi)

18/ pi = r

Using 3.14 for pi

18/ 3.14 = r

5.732484076 = r
