Find the radius of the circle if the length of the bounding arc is 286 Pi.

Using the conditional variable “Y”, we denote the unknown unknown radius of the circle.

Applying the data of this example and taking into account the formula for the circumference of a circle, we compose the following expression: 286 x 3.14 = 2 x 3.14 x Y.

When we make the calculations, we will have the following result Y = 286/2 = 143.

Answer: The radius of the circle is 143.
