A curvy line is that is used for rounded angles. This makes it easier to measure.
A tape measurer can be used to measure distance in linear or even around curved surfaces. It is an old tool that has a neat history. See the related link for more information.
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.

No, it can't, for curved edges you use a piercing saw!

A caliper or a micrometer is typically used to measure curved lines in a laboratory setting. These instruments provide precise measurements of the length or diameter of curved objects such as tubes or spherical surfaces.
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.

The curved line over a short vowel is called a breve. It is used to indicate a short pronunciation of the vowel.
A spherometer is used to measure the radius of curvature of a curved surface, such as a lens or mirror. It typically consists of three adjustable legs that can be used to determine the radius of the curved surface by measuring the height variation across the surface.

A white line with a curved arrow pointing the way you must go.
A graduated cylinder is used to measure liquid volume in milliliters, mL. When you place a liquid into a glass graduated cylinder, you will see that the "line" at the top of the column of liquid is actually curved downward. This is called the meniscus. When you measure the liquid volume, you record the volume in mL at the bottom of the meniscus.
