Question

1. The circumference of a circle is 39.6 cm. Find its area.​

Answer 1

$circumference = 2\pi\ r = 39.6cm \\ => 2 \times 3.14 \times r = 39.6 \\ = > r = 6.3$

$area = \pi {r}^{2} \\ 3.14 \times 6.3 \times 6.3 = 124.68 \: c {m}^{2}$

HOPE THAT HELPS YOU, THANK YOU, GOOD AFTERNOON

Answer 2

Answer:

$given \: circumference \: of \: circle \: = \: 39.6 \: cm \\ = = = = > \:2 \times \frac{22}{7} r \: = 39.6 \\ = = = = > 44r \: = 39.6 \times 7 \\ = = = = > r = \frac{39.6 \times 7}{44} \\ = = = = = > r = 6.3 \: cm \\ area \: of \: circle \: = π {r}^{2} \\ = = = = > \frac{22}{7} \times 6.3 \times 6.3 \\ = = \: = = > 124.74 \: sq.cm$
