Answer» Let radius be r cm We are given, Circumference, 2πr = 44 so,πr = 22 so, 22/7r = 22 r = 7 cm So, area of Quadrant = 1/4 πr² = 1/4 * 22/7 * 77 = 227/4 = 154/4 = 38.5 cm² hit like if you find it useful

Answer»

Let radius be r cm

We are given, Circumference, 2πr = 44 so,πr = 22 so, 22/7*r = 22 r = 7 cm

So, area of Quadrant = 1/4 *πr² = 1/4 * 22/7 * 7*7 = 22*7/4 = 154/4 = 38.5 cm²
