# What is the radius of a circle with circumference of 5 cm?

Nov 4, 2015

$0.796$ $\text{cm}$

#### Explanation:

Circumference $= 2 \pi r$

$5 = 2 \pi r$

$r = \frac{5}{2 \pi}$

$r = 0.796$

r = 0796 is right answer.

#### Explanation:

It can be fuhrer explained as under :-

Formula for radius is : -
Since

$C i r c u m f e r e n c e , C = 2 \pi r$

Hence

$r = C / 2 \pi$

Here ,

C = 5
$\pi = \frac{22}{7} \mathmr{and} 3.14$

Hence by putting value in formula $r = C / 2 \pi$

$r = 5 / 2 \pi$
or

$r = 5 / 2 \cdot \frac{22}{7}$

or

$r = 5 / 2 \cdot 3.14$

or

$r = 5 / 6.18$

or

$r = 0.796$
