You know the length of a chord and the distance it is from the center of a circle. How do you find the length of the radius?
Let's step through this one and knock it down. Draw a circle and a chord. Now add a radius to the circle that bisects the chord. It will form right angles with that chord, right? Yes, it will. Now add another radius from the center to one end of the chord where it intersects the circumference of the circle. You should have a right triangle, and one side is composed of half the length of the chord. The other side is that short segment between the chord and the center of the circle. The hypotenuse of the triangle is the radius of the circle, which is the last thing we drew in. Now let's do the math à la Pythagorus. You remember him. The sum of the squares of two sides of any right triangle is equal to the square of the hypotenuse. Yeah, that guy. You know the distance to the chord from the center of the circle. Put that on the drawing. You also know the chord length, and half of that will be the length of the other side of the right triangle you created. You have the lengths of two sides of the right triangle. Now square each side, add them together and take the square root of that to discover the length of the hypotenuse - which is the radius of the circle. Piece of cake. Want a sample problem? Why not. The length of a chord of a circle is 24 units. The chord is 5 units from the center of the circle. Remember our right triangle? It has side lengths of 5 units and 24 divided by 2 or 12 units. The 5 squared is 25 and the 12 squared is 144, and 25 plus 144 equals 169. The (positive) square root of 169 is 13, and our radius is 13 units long. Simple and easy. Just like Pythagoras or any of his students would handle the problem.

Which are the examples and non examples of radius in math?
Some examples and non example of a radius in math are: Examples - the distance from the center of a ball to the outer edge. The difference from the center of a circle to the outer edge. Non example - the length of a square, the entire length across a circle or ball, the distance around the perimeter of a circle.
A line segment with one endpoint at the center of a circle?
The answer depends on where the other end of the line segment is. If it is on the circumference the segment is a radius. Otherwise, it is indeterminate.
What is the unit used to measure distances around a circle?
Radian is the unit used to measure distances around a circle. It is defined as the angle subtended at the center of a circle by an arc equal in length to the radius of the circle.
What is the radius?
One of the most important functions of the radius is anchoring the muscles of the upper arm and the forearm. It is found on the thumb side of the forearm and rotates to allow the hand to pivot at the wrist.
If Earth's radius was 3960 miles how long would the length of the Equator be?
The length of the equator would be approximately 24881.4 miles. Using the circumference formula 2(pi)(r) where pi is 3.141592654... and r is the radius (3960 in this case) you can find the length of the circle, the equator. 7920 in reality, is the diameter which is distance of a single straight line that starts and ends on the circle and passes through the center of the circle.
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 is the difintion for radius?
A radius is the distance from the center of a circle, to the border. In a circle, all radii have the same length.
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 do you call a circle with a dot in the middle in radius and diameter?
The distance from a circle to its center (the dot in the middle) is called 'the radius'. The distance from a circle to a point opposite is called 'the diameter'. The diameter is twice the length of the radius.
One radius of a circle is the same length as any other radius of any other radius?
The radius is the distance from the center of the circle to its edge. No matter how you draw this radius, it is one value of one length only, for any given circle.
Which term is defined as the distance from the center of a circle to any point on the circle?
The term defined as the distance from the center of a circle to any point on the circle is called the "radius." The radius is a crucial element in the geometry of circles, as it helps determine the circle's size and area. It is half the length of the diameter, which is the distance across the circle through its center.
What is the length of the radius of the circle?
The radius of a circle is the length of the line from the center of the circle to any point on its edge.
What is the distance from the center of a circle to its circumstances?
It is its radius that is the distance from the center of the circle to its circumference.
What is the distance from a circle to it's center?
It is called the radius. The full distance is called the diameter.
What is the distance between the center of a circle and a point on the circle?
The radius is the distance between the center of a circle and a point on the circle
Distance to the center of a circle?
radius
The distance from a circle to its center is its?
