Question

The circumference of the circle is 22m find its area​

Answer 1

Circumference = 2πr

$\large \: 22 = 2 \times \frac{22}{7} \times r \\ \\ r = \frac{7}{2}$

$\large \: area \: = \pi \: r ^{2} \\ \\ \frac{22}{7} \times \frac{7}{2} \times \frac{7}{2} \\ \\ \\ \frac{22}{7} \times \frac{49}{4} \\ \\ = \frac{77}{2}$
