1.	The primeter of the quadrant of a circle is 25 cm .find its area
Answer» Let radius = rPerimeter = radius + radius + length of arcPerimeter of quadrant = r + r + angle/360 * 2 * pi * r = 252r + [1/4 * 2 * 22/7 * r] = 2525/7 * r = 25r = 7Area = angle/ 360 * pi * r * r1/4 * 22/7 * 7 * 7 = 38.5 sq.cm
