Let the radius of the circle = r m The circumference of the circle = 22m (given) [tex] = > \: \: 2\pi \: r = 22[/tex] [tex] = > r = \frac{22}{2\pi} = \frac{22 \times 7}{2 \times 22} = \frac{7}{2} m[/tex] Hence, area of the circle [tex] = \pi \: r {}^{2} = \frac{22}{7} \times \frac{7}{2} \times \frac{7}{2} = \frac{11 \times 7}{2} = 38.5 \: m {}^{2} [/tex]
