What is the length of a line with endpoints
To find the length of this line, you can subtract 
to get 
. Since the y-coordinates are the same, you don't have to take any vertical direction into account. Therefore, you only look at the x-coordinates!
To find the length of this line, you can subtract

lies on a circle. What is the length of the radius of the circle if the center is located at 
?
The point
The radius is the distance from the center of the circle to anypoint on the circle. So we can use the distance formula in order to find the radius of the circle:

The radius of a circle is 6 inches. What is one-third of the diameter?
The radius of a circle is 6 inches. What is one-third of the diameter?
If the radius is equal to 6 inches, then the diameter will be double that value, or 12 inches. One-third of 12 is 4, which is therefore the correct answer.

If a circle has a radius of 12 inches, the biggest line that would be drawn within the circle is:
If a circle has a radius of 12 inches, the biggest line that would be drawn within the circle is:
The largest line that can be drawn within a circle is the diamater. The diameter is equal to twice the radius. Given that the radius is equal to 12 inches, the largest line that could be drawn (the diameter) would be equal to 24 inches.

A right triangle has one leg with a length of 6 feet and a hypotenuse of 10 feet. What is the length of the other leg?
A right triangle has one leg with a length of 6 feet and a hypotenuse of 10 feet. What is the length of the other leg?
In geometry, a right angle triangle can occur with the ratio of 
in which 3 and 4 are each leg lengths, and 5 is the hypotenuse.
When you know the length of two sides of a right angle triangle like this, you can calculate the third side using this ratio.
Here, the ratio is:
This is double the 
ratio. Therefore, we should multiply 4 by 2 in order to solve for the missing leg, which would be a value of 8 feet.
Another way to solve is to use the Pythagorean Theorem: 
.
We know that one leg is 6 feet and the hypotenuse is 10 feet.

. It is bisected at point 
, and the resulting segment 
is bisected again at point 
. What is the length of the line segment 
?
Line
A line that is bisected is split into two segments of equal length. Therefore, if line 
is bisected at point 
,
.
Consequently, bisecting line segment
