Find the length of an arc 5/12 of a circle with a radius equal to 36dm.

The required unsettled length of the circular arc is defined by the conditional variable “Y”.

Based on the information in this example and using the formula for the circumference of a circle, we compose the following expression: Y = 2 x 3.14 x 36 x 5/12.

When we make the calculation, we get the following total Y = 2 x 3.14 x 3 x 5 = 6 x 5 x 3.14 = 30 x 3.14 = 90.42 dm.

Answer: the length of the arc of a circle is 90.42 dm.
