Question

What is the radius of a circle that has a circumference of 3.14 meters?

Answer 1

Hola there..

Circumference = 3.14 m

=> 2πr = 3.14

=> r = 3.14/(2×3.14)

=> r = 1/2

=> r = 0.5 m.

Thanks :)

Answer 2

$\underline\textbf{Circumference \:of\: circle}$ = 2πr

$\underline\bold{Given\: circumference\:in\: Question}$= 3.14

2πr = Circumference of circle .

Putting of values in the given formula.

We can take π as 3.14 or $\dfrac{22}{7}$

After putting the values we will get this equation .
$\boxed{\bold{2 \:×\:\:3.14\:r\:= \:3.14}}$

2 × 3.14 r = 3.14

6.28 r = 3.14

r = $\dfrac{3.14}{6.28}$

r = 0.5 m
