<em>Answer:</em>
<em>x = (k + c)/4</em>
<em>Step-by-step explanation:</em>
<em>4x - c = k</em>
<em>4x = k + c</em>
<em>x = (k + c)/4</em>
Given:
Circumference of a circle = C
Diameter of a circle = d
To find:
The relationship between the circumference, c, and diameter, d, of any circle.
Solution:
We know that, circumference of a circle is

It can be written as

![[\because d=2r]](https://tex.z-dn.net/?f=%5B%5Cbecause%20d%3D2r%5D)
On dividing both sides by d, we get

Therefore, the correct option is (F).
Answer:
