If the chord is 5 cm, and the radius is 13 cm, a right triangle is formed between the lines. The hypotenuse of this right triangle is 13 cm, and one of the sides is 5 cm. We know that the second side is half of the chord distance. Therefore, we use the Pythagorean Theorem:
5^2 + b^2 = 13^2
25 + b^2 = 169
b^2 = 144
The square root of 144 is 12. Therefore, b = 12. However, this is only half of the chord length. Multiply 12 by 2 and you get 24. Therefore, 24 cm is the answer.
Hope that was helpful...it may have been hard to understand without a visual.

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.
If the diameter is 32 centimeters what is the radius in centimeters?
The radius of a circle is half the length of the diameter, so if the diameter is 32 centimeters the radius is 16 centimeters.
Can a circle be drawn with any center and any radius?
The center of a circle is the same for all circles but the length of the radius can change
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.
How is the diameter and radius similar?
diameter is 2 times the length of the radius and is a line straight through the center of the circle. radius is half of the diameter and is a line from the center to a edge of the circle
If the diameter of a circle is 4 centimeters what is the length of the radius?
Length of a radius is always half the diameter of a circle. This means that the circle has a radius of 2cm.
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.
If the diameter is 32 centimeters what is the radius in centimeters?
The radius of a circle is half the length of the diameter, so if the diameter is 32 centimeters the radius is 16 centimeters.
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.
Can a circle be drawn with any center and any radius?
The center of a circle is the same for all circles but the length of the radius can change
If the diameter of a circle is 7.5 centimeters what is the length of the radius?
D=3.75
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 length from a circle's center to its circumference called?
the radius
Segment that has one endpiont at the center and the other endpoint on the circle?
A radius of a circle is a line segment joining the center of the circle to a point on the circle. All such segments have the same length, and this length also called the radius of the circle.
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.
Is a radius part of a circle?
Yes it is. The radius of a circle is the length of the line from the center to any point on its edge.
What is the radius of the circle equal to?
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
