Longitude
A circle with a straight line through it, usually at an angle, and often with a small dot where the centre of the circle would be (also on the line, to clarify that the line does go through the centre).
Line through the center of a circle is the diameter or distance across the circle.
Radius is half the diameter. The diameter of a circle is a straight line that passes from one side of the circle to the other through the centre of the circle. Half of that line is the radius.
The diameter of a circle is a straight line going from one point on its boundary, through the centre of the circle, to the boundary on the other side.
Draw a line from the edge, through the centre, to the other side - both pieces will be equal.
Any line through the centre.
360 degrees * * * * * That is a nonsensical answer. The diameter of a circle is a straight line segment, going from the circumference of the circle, through the centre, to the circumference on the other side.
The diameter is the length of a straight line, from one side of the circle to the other, passing through the centre. The radius is a straight line from the circle centre to the circle itself and is always = half the length of the diameter, so 6 * 0.5 = 3
A diameter is a straight line from one side of a circle, through the centre, to the other side. A circumference is the curved line forming the boundary of a circle.
a chord. The chord that passes through the center of the circle has a special name: the diameter.
Construct a circle with a compass and then draw a straight line through its centre
Circumference (perimeter) of a circle = pi x diameter Diameter of a circle is the straight line distance from one side to the other which passes through the centre of the circle.
