Question
In a trapezium, the lengths of the parallel sides are 18
cm and 24 cm, and the height is 12 cm. A circle is inscribed in the trapezium. Find the radius of the circle.Solution
The radius of the inscribed circle in a trapezium is given by the formula: r = (h) / 2, where h is the height of the trapezium. Substitute the value of the height (12 cm): r = 12 / 2 = 6 cm.
