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

Answer:

38.5 cm^2

Step-by-step explanation:

Circumference of circle = 2\pi r

Since we are given that circumference is 44 cm

2\pi r=44

Use \pi = \frac{22}{7}

2\times \frac{22}{7} \times r=44

 r=44 \times \frac{7}{22} \times\frac{1}{2}

 r=7cm

Now Formula of area of quadrant = \frac{1}{4} \pi r^{2}

                                                        = \frac{1}{4}\times \frac{22}{7}\times7^{2}

                                                        = \frac{1}{4}\times \frac{22}{7} \times 49

                                                        = 38.5 cm^2

Hence the area of quadrant is  38.5 cm^2
