What is the diameter of a circle?
A chord of a circle is a straight line that joins any two points on the circumference of a circle. The diameter of a circle is the length of the chord that passes through the centre of the circle; it is the chord of longest length and is twice the radius of the circle in length.
Meaning of diameter in a circle?
The diameter of a circle is the length of the circle from one side to the other, going through the middle of the circle. The radius is the measurement of length from the middle of the circle to the perimeter of the circle. This is half of the diameter.
What does the radius and diameter have in common?
They both describe a circle. The radius is the length from the middle of the circle to the edge. The diameter is the length of a straight line going through the middle of the circle edge to edge.
When a circle is drawn through each vertex of a right triangle the triangles hypotenuse will be equal to what?
The length of the circle's diameter
What does diameter mean in relation to math?
It is in a diameter of a circle, which is bassicly means the length of a circle, right through the middle.

How do you determine length and width of a circle?
there is no length or width of a circle. There is radius and circumference and the line that goes all the way through the center to the other side of the circle, which is twice the radius. But there is no length or width of a circle.

What is the diameter of a cirlce?
The length of a chord that passes through the center of a circle is the diameter of the 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.
Is it possible for a chord of a circle to be the length as the diameter of that same circle?
Absolutely! As long as the chord goes through the center of the circle.
What does the radius and diameter have in common?
They both describe a circle. The radius is the length from the middle of the circle to the edge. The diameter is the length of a straight line going through the middle of the circle edge to edge.
When a circle is drawn through each vertex of a right triangle the triangles hypotenuse will be equal to what?
The length of the circle's diameter
If you know the length of a radius of a circle how can you find the length of the diameter?
The diameter of a circle is 2 times the radius. The radius of a circle is the distance from any point on the circle to the center of the circle, and the diameter is the distance from one side of the circle to the opposite side, passing through the center.
What does diameter mean in relation to math?
It is in a diameter of a circle, which is bassicly means the length of a circle, right through the middle.
What is a line segment that has both endpoints on the circle?
This is referred to as a chord. If the chord passes through the center of the circle, it represents the diameteror width of the circle.For a circle, the length of the diameter is the longest possible length of a chord.
What mean of Pi related to circle?
Pi is the ratio of the circumference (the length going around the outside of the circle) to its diameter (the length going across the circle and through the center). Pi is constant for all circles.
