The diameter of the circle is 13 dm, calculate its area.

We express the required unsettled area of the circle using the conditional variable “Y”.

Based on the information in this example and using the formula for the area of a circle, we will compose the following expression: Y = 3.14 x 13 x 13/4.

The result of the calculation will be Y = 0.785 x 169 = 132.665 dm ^ 2.

Answer: 132.665 dm ^ 2.
