# What is the length of arc AB?

Space and Astronomy10π5/18 of the circumference of the circle, which equals 2πr, according to the formula for circumference. length of arc AB = (5/18)(2πr) = (5/18)(2π(18)) = 10π. Thus, the length of arc AB is 10π.

## How do you find the length of arc AB?

**How do you calculate arc length without the angle?**

- Divide the chord length by double the radius.
- Find the inverse sine of the result (in radians).
- Double the result of the inverse sine to get the central angle in radians.
- Once you have the central angle in radians, multiply it by the radius to get the arc length.

## How do you find the length of AB on a graph?

Video quote: *So the length of segment a B is equal to we're going to do is take the difference in the x-values square.*

## How do you calculate length?

Video quote: *So in this example we have the data area is equal to 500 meter square width is equal to 10 meter to calculate the length we have the formula length is equal to area divided by width W.*

## How do you find the length?

**Depending on what information you have available, there are many ways to calculate the length of a rectangle.**

- If you have the area A and width w , its length w is determined as h = A/w .
- If you have the perimeter P and width w , its length can be found with h = P/2−w .

## What is the formula for the length of a line?

To use the distance formula to find the length of a line, start by finding the coordinates of the line segment’s endpoints. Then, plug the coordinates into the distance formula. Next, **subtract the numbers in parenthesis and then square the differences**.

## What is the length of line segment AB the diagonal of rectangle ABCD measures 2 inches in length?

√3 inches

The diagonal of the rectangle ABCD measures 2 inches in length. The length of line segment AB is **√3 inches**.

## How do you find the length of the slope of a line?

The slope length is calculated using the Pythagorean Theorem, where the vertical distance is the rise and the horizontal distance is the run: **rise ^{2} + run^{2} = slope length^{2}**.

## How do you find the length of a line between two points?

The linear distance between the two points is **the square root of the sum of the squared values of the x-axis distance and the y-axis distance**. To carry on the example: the distance between (3,2) and (7,8) is sqrt (52), or approximately 7.21 units.

## What is length of segment?

**The distance between two points on a line segment** is called the length of the segment. We usually use the same symbol for the length of the line segment that we use for the segment itself.

## What is the length of segment QV?

parallel. perpendicular. skew. In the diagram, the length of segment QV is **15 units**.

## How do you find the segment length?

Answer: The length of a line segment can be measured by **measuring the distance between its two endpoints**. It is the path between the two points with a definite length that can be measured. Explanation: On a graph, the length of a line segment can be found by using the distance formula between its endpoints.

## What is the length of segment TQ?

Segment TQ is **26 units** long.

## Is Janelle correct quizlet?

Is Janelle correct? **No, because the lines are in the same plane.**

## Is Janelle correct?

Is Janelle correct? C. **No, because the lines are in the same plane.**

## What is the length of segment TQ quizlet?

Segment TQ is **26 units** long.

## Which lines are parallel justify your answer?

**If two lines are cut by a transversal and alternate interior angles are congruent**, then the lines are parallel. If two lines are cut by a transversal and same-side interior angles are supplementary, then the lines are parallel.

## Is Kevin correct no because they are non coplanar no because they are parallel yes because they are perpendicular yes because they are coplanar?

Kevin says that lines p and m will eventually intersect. Is Kevin correct? **No, because they are non-coplanar.**

## How are lines KL and MN related?

How are lines KL and MN related? **The lines intersect at point K.** **The lines are parallel.**

## What is the value of a two parallel lines are crossed by a transversal?

Two parallel lines are crossed by a transversal. The value of x is **115°**.
