Question

Find the area of a quadrant of a circle whose circumference is 22 cm.​

Answer 1

Answer:

77/8 square cms.

Step-by-step explanation:

$circumference = 2\pi \times r \\ \\ = 2 \times \frac{22}{7} \times r = 22 \\ \\ r = \frac{7}{2} = 3.5 \: cm \\ \\ area \: of \: a \: quadrant = \frac{\pi {r}^{2} }{4} \\ \\ = \frac{1}{4} \times \frac{22}{7} \times \frac{7}{2} \times \frac{7}{2} \\ \\ = \frac{11 \times 7}{8} \\ \\ = \frac{77}{8} \: square \: cms.$
