| **The radius of the circle is 60 m. Find the circumference to the nearest millimeter. Find the length of the arc corresponding to the 90 degree angle**

The length of a circle can be calculated using the formula:

L = 2ПR, where L is the circumference, П is the number of Pi, R is the radius of the circle.

П = 3.14;

L = 2 * 3.14 * 60mm = 376.8mm.

You can notice that the circle corresponds to 3600, and 900 is 1/4 of 3600, which means that the length of the arc corresponding to the angle 900 will be L * 1/4 = 376.8 * 1/4 = 94.2 mm.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
