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

circle = is 6.28
π=3.14

Answer 2

Answer:
`r=(C)/(2\pi)`, where C is the circumference of the circle.

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

`(C)/(2\pi)=r`

OR

`r=(C)/(2\pi)`

Hence, the expression for r will be:-

`r=(C)/(2\pi)`, where C is the circumference of the circle.
