Example Question #1 : How To Find Length Of A Line
What is the length of a line with endpoints and .
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!
Example Question #182 : Plane Geometry
Find the length of the line segment whose endpoints are and .
We can use the distance formula:
Example Question #2 : How To Find Length Of A Line
The point lies on a circle. What is the length of the radius of the circle if the center is located at ?
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:
Example Question #3 : Lines
The coordinates of and are and . Find the length of the diagonal of the following rectangle:
A rectangle has two diagonals with the same length. So we should find the length of . We can use the distance formula:
Example Question #11 : How To Find Length Of A Line
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.
Example Question #12 : How To Find Length Of A Line
The diameter of a circle is centimeters. What is one-fourth of the circle's radius?
By definition, the radius and diameter of a circle are related by the following equation:
Plugging in as stated in the question, we find that .
Since the question is asking us for the value of :
.
