With the help of the conditional variable “Y” we denote the required length of the circular arc corresponding to an angle of 135 ℃.
The first step is to determine the length of the entire circle.
Using the formula for the circumference of a circle, we get 2 x 3.14 x 6 = 37.68 m.
Using the example data, we get the following proportion: 37.68 m refers to 360 ℃, as U m refers to 135 ℃.
Taking into account the proportional conditions, we get Y x 360 = 37.68 x 135.
When we count, we will have Y = 37.68 x 135/360 = 14.13 m.
Answer: 14.13 m.
