Answer 2

Finding the Radius of the Inscribed Circle in a Quadrilateral

To find the radius of the inscribed circle in a quadrilateral, we need to know the perimeter of the quadrilateral. In this case, the perimeter is given as 16 cm.

Let's denote the sides of the quadrilateral as AB, BC, CD, and DA. The radius of the inscribed circle can be found using the formula:

Radius = (Perimeter of the Quadrilateral) / (2 * (Sum of Adjacent Sides)).

In this case, the perimeter of the quadrilateral is 16 cm. However, we don't have information about the lengths of the sides of the quadrilateral. Therefore, without additional information, it is not possible to determine the radius of the inscribed circle.

If you have any additional information or if there is anything else I can help you with, please let me know!
