The radius of a circle or sphere is a straight line from the centre to the edge.
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.
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.
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.
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!)
Diameter runs straight across. Radius only goes half way, to the center.
The radius of a circle or sphere is a straight line from the centre to the edge.
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.
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.
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.
It is the radius of a circle
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.
It is the radius.
The radius.
Its radius.
A straight line from the center of a circle to the outer edge is called a radius.
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.
