Also, as a girl, we do give some signs to people that we like, we start conversations with the person, we make eye contact and then look away (at least that what I do lol), flirts with you, agrees with you, wants to spend time with you, etc.
radius is the distance from the centre of a circle to any given point on its circumference, diameter is the length between two points that are the furthest possible from each other on the circle's circumference.
The diameter is twice the radius.
Therefore, if the radius is 12in then the diameter is 24in.
