Answer 1

Mark as BRAINLIEST.

A curved line, also called an "arc," represents a portion of a circle. It is difficult to measure a curve with a straight-edged ruler with any kind of accuracy, but geometry provides a relatively simple way to calculate the length of an arc. You'll need a tool called a protractor and some basic information. You must also know the diameter of the circle. Then, you can apply the following formula: length of an arc = diameter x 3.14 x the angle divided by 360.

Answer 2

Answer:

Explanation:

The length of a curved line can be easily measured with the help of a string. Place the string on the curved line and trace the shape it takes.
