You can measure the length of a curved line by using a flexible measuring tape following the curve or by breaking it down into smaller straight segments and adding them up. Another option is to use a formula that calculates the arc length of a curve based on its equation and limits.

What do you measure with length?
Length is a physical quantity that measures the extent of something along a straight line. Common units used to measure length include meters, centimeters, inches, and feet. Length is commonly used to describe the size and distance of objects.
Does the focal length of a convex lens get smaller when they become more curved?
Yes, as a convex lens becomes more curved, its focal length decreases. This is because a more curved lens causes light rays to converge at a point closer to the lens, resulting in a shorter focal length.
In a lens an imaginary line that would pass through the center of the lens perpendicular to its curved surfaces?
The line passing through the center of the lens perpendicular to its curved surfaces is called the principal axis. This axis is used as a reference point for measuring distances and angles in optics. It helps determine the focal point and focal length of the lens.
Is it possible to measure the length of a ray?
It is impossible to measure the length of a ray, because a ray is a line with one stopping point, and one never ending point. You can measure the angle between two connected rays though. Source(s): I'm an expert at Math and Science.
What can measure liquid?
A graduated cylinder, measuring cup, or beaker can be used to measure liquid volume accurately. It is important to use the correct measuring tool and ensure the meniscus (the curved surface of the liquid) is at the correct measurement line for accuracy.
How will you measure the length of a curved line using divider?
first we will put the divider in the starting of line then we will make points than we can measure it.
What instrument would be most suitable for measuring length of a curved line?
Standard flexible tape measure
The length of a long curved line?
long
How do you measure a curved line on a map?
You can measure a curved line on a map by using a string or measuring tape to match the curve and then measuring the length against a ruler or a map scale. Alternatively, you can break down the curve into smaller straight line segments and then add up their lengths to get an estimate.
How does one find the length of an arc?
An arc length is the measure of the distance along the curved line making up the arc. It is longer than the straight line distance between the two end points.
How can we measure the length of curved line by using thread and divider?
To measure the length of a curved line using a thread and divider, first, place the thread along the curve, ensuring it follows the curvature closely without any slack. Once the thread is laid out along the entire length of the curve, mark the point where it meets the starting point. Then, remove the thread and use a ruler to measure the length of the section of the thread that corresponds to the curve. Alternatively, you can use the divider to mark intervals along the thread and then measure those intervals to get a more accurate length.
What are two instruments that could be used to measure curved lines?
Two instruments that could be used to measure curved lines are a flexible ruler and a caliper. A flexible ruler, also known as a contour gauge, can be molded to the shape of the curved line to measure its length accurately. A caliper, specifically a vernier caliper, can be used to measure the diameter or thickness of a curved object by gently gripping and measuring across the curve.
How you measure curved line with thread?
Use a thread to measure the length of curved line AB. Put a knot on the thread near one of its end. Place this knot on on point A. Now, place a small portion of thread along the line, keeping it taut using your fingers and thumbs. Hold the thread at this end point with one hand. Using other hand, stretch a little more portion of the thread along the curved line. Go on repeating this process till the other end B of the curved line is reached
What can be measure by length?
a line.
What does it mean for a straight line such as a radius to be equal in length to a curved line such as an arc of a circle?
Length of any curve is imagined as an infinite sum of the lengths of infinitely small straight sections. If you look at a part of circle under a microscope you cannot tell that it is curved. This idea is used extensively in the branch of mathematics call "integral calculus". On a practical level, you can lay out a circle with a length of wire, then straighten it out to measure its length.
How can the length be measured along a curved line?
Put a string over the curved line. Measure the string. If you want to do it by calculations for some known function, use integration. Divide the curved line into many small pieces, so that each piece can be approximated by a straight line, and use Pythagoras' Formula for each piece: length = square root of (width2 + height2), using the width and height of the piece. In calculus books, you'll find methods that can get you an exact result in some cases.
What is the length of a line?
A line does not have a definite length .It extends to infinity.Whereas a line segment has a definite measure.
