The radius of the circle is 60 m. Find the circumference to the nearest millimeter.

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.
