Question

the circumference of a circle can be found using c=2/pi r. use the formula to solve for the radius of a circle, r.

Answer 1

Answer:  $r=\dfrac{C}{2\pi}$, where C is the circumference of the circle.

Step-by-step explanation:

We know that the formula to calculate the circumference of the circle is given by :-

$C=2\pi r$, where r is the radius of the circle.

To find the expression for r , we divide $2\pi$ on the both sides , we get

$\dfrac{C}{2\pi}=r$

OR

$r=\dfrac{C}{2\pi}$

Hence, the expression for r will be:-

 $r=\dfrac{C}{2\pi}$, where C is the circumference of the circle.

Answer 2

Circle = is 6.28 
π=3.14
