Question

The circumference of a circle is 364 cm, find its area.​

Answer 1

Step-by-step explanation:

$circumference(2\pi \times r) = 364 \\ 2\pi \: r = 364 \\ 2 \times \frac{22}{7} \times r = 364 \\ r = \frac{364 \times 7}{2 \times 22} \\ r = 8.27 \times 7 \\ r = 57.89cm \\ \\ area \: of \: circle \\ \pi \times {r}^{2} = \frac{22}{7} \times 57.89 \times 57.89 \\ = 10532.50 \: c {m}^{2}$
