Example Questions
Example Question #11 : Lines
If a circle has a radius of , what would be the length of the longest line drawn within that circle?
The diameter of the circle would be the longest line that can be drawn within that circle.
Because radius is half of the diameter, the diameter is calculated by multiplying the radius of the circle by two.
If the radius is , then the diameter is
Example Question #12 : How To Find Length Of A Line
A ladder is leaning on a wall. It is ft long. The bottom of the ladder is from the base. How far up the wall is the top of the ladder?
The Pythagorean Theorem states that:
With and representing the measurement of the legs and representing the hypotenuse.
Example Question #13 : How To Find Length Of A Line
What is the perimeter of a right triangle if the hypotenuse is and the measurement of one of its legs is
First, use the Pythagorean Theorem to get the measurement of the other leg.
To get the perimeter of the triangle, add the measurements of each of the three sides.
Example Question #14 : How To Find Length Of A Line
A line has endpoints and What is the distance of the line?
Use the distance formula
Example Question #15 : How To Find Length Of A Line
Line has a length of It is bisected at point , and the resulting segment is bisected again at point What is the length of line segment
First, write each portion of the statement in mathematical terms.
Since AB=80 we will substitute that into the equation.
Now that we know AC we can calculate AD as follows.
Example Question #13 : How To Find Length Of A Line
The point lies on a circle. What is the approximate length of the radius of the circle if the center is
Because the radius is the distance from center to any point on a circle, the distance formula is used to find the measurement of the radius.
Example Question #14 : How To Find Length Of A Line
If the diameter of a circle is , then what is of the circle's radius?
Radius is of the diameter.
If the diameter is , then the radius is
Therefore
of is,
.
Example Question #82 : Plane Geometry
Find the slope of a line that passes through and .
The slope is undefined.
Use the slope formula to solve:
Given the following points.
The slope can be calculated as follows.
Because the coordinates were the same for points A and B, this would form a horizontal line. The slope of any horizontal line is
Example Question #12 : Lines
Find the length of a line from the point to the point .
Find the length of a line from the point to the point .
To find this distance, we need to use distance formula (which is really similar to Pythagorean Theorem)
Distance formula is as follows
Where our x's and y's come from our ordered pairs.
So, let's plug and chug
Simplify
So our answer is 30.4
Example Question #1911 : Isee Middle Level (Grades 7 8) Mathematics Achievement
What is the length of a line segment with end points and ?
The length of a line segment can be determined using the distance formula:
