No they are two separate lines on the London Underground. Circle line is yellow ,Central line is black I think.
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.
A circle.
The line of zero latitude, also known as the "equator", is.It's roughly 24,800 miles long.
That line is the most central line and is called the Circle Line.Operating round the central of London it's a surprise it isn't called the Central Line.But there is a Central Line, and a section of it runs just north of Westminster.
The bass clef is also known as the 'f' clef (because the line in-between the two dots is the note f). The treble clef is also known as the 'g' clef (because the line that the circle in the middle is on is the note g).
Green is the District Line
The radius of a circle is one half of the circle's diameter, any line going from the center of the circle to the circle itself. A line connecting other points on a circle (or on any curve) is called a chord.
A chord is a straight line that spans the circumference of a circle and the diameter of a circle is a straight line in a circle spanning its circumference and passing through the circle's centre.
The radius of a circle is any straight line from the centre of the circle to its circumference. The radius can also refer to the length of this line.
A circle is a line, drawn around a point in such a way that the line is always the same distance from the point. This distance is known as the 'radius' of that circle.
The Circle Line and Central Line run between these two stations.
That's known as the circumference.
