How do we find the diameter of a circle?

If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.

Does diameter mean width?

Diameter is the length of a line touching two points on a circle that passes through the center. Diameter exists only for circular, or for circle-based objects like a sphere or cylinder, thus the width and length should always be the same. The diameter is the same as the length or width of any circle.
