What is the radius of circle?
The radius of a circle or sphere is a straight line from the centre to the edge.
What happens between a radius and a tangent in a circle?
A tangent is always perpendicular to the radius of a circle. A radius is a straight line going from the center of the circle to the circumference (edge) of the circle. A tangent is a straight line outside the circle that touched the circle at one (and only one) point. When a tangent touches the outside edge of the circle at the same point where a radius touches the edge of the circle, the angle between the radius and tangent line is 90 degrees meaning they are perpendicular.
What is it called when a line goes halfway across a circle?
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.
What is difference between a radius and a diameter?
Radius is the shortest distance via straight line between the center point of the circle and its perimeter. Diameter is the greatest distance via straight line from one perimeter of the circle to the opposite perimeter. Diameter = 2x Radius.
Is the radius of a circle a chord also?
No. A chord is a straight line joining two points on the circumference of a circle whereas a radius joins only one point on the circumference to the circle centre. A diameter is a straight line joining two points on the circumference (via the circle's centre) and so is also a chord. (Yes, but the question is about a radius, not a diameter!)
What is the line that runs straight across a circle?
Diameter runs straight across. Radius only goes half way, to the center.
What is the radius of circle?
The radius of a circle or sphere is a straight line from the centre to the edge.
Diameter to radius?
Diameter- A line going straight from side to side of a circle, equals the total distance across the circle. Radius- Half of the total diameter. For example, if the diameter is 8, the radius is 4.
How do you find the radious of a circle?
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.
What is radius?
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.
What is a straight line fom the centre of the circle to the edge?
It is the radius of a circle
How do you change a diameter in radius?
The diameter of a circle is the length of a straight line that goes through the exact center of a circle. The radius of a circle is the length of a straight line that starts at the exact center and reaches the circle. The radius is half the length of the diameter.
A straight line from the center of a circle to the circumference?
It is the radius.
What is a Straight line from the centre to the circumference of a circle?
The radius.
A straight line from the center to the perimeter of a circle?
Its radius.
Which term describe the distance from the center of a circle to any point on the circle?
The distance from the center of a circle to any point on the circle is called the radius of the circle. The radius is a line segment that starts at the center of the circle and ends at any point on the circle. It is always a straight line and is always perpendicular to the circumference of the circle. The radius is half the diameter of the circle, which is the distance across the circle through the center. The diameter of a circle is always twice the length of the radius.

What is a straight line from the centre to the edge of a circle called?
A straight line from the center of a circle to the outer edge is called a radius.
