Step-by-step explanation:

$Given , \: \: Circumference \\ \: of \: circle = 198m$

$now, we \: know \: that ,$

$Circumference \: of \: circle = 2πr$

$=> 2× \frac{22}{7} ×r = 198$

$=> r= \frac{198×7}{22 \times 2}$

$=> r = \frac{99 \times 7}{22}$

$=> r = \frac{693}{22}$

$now , \: area = πr²$

$= \frac{22}{7} ×\frac{693}{22} m²$

$= \frac{693}{7} m²$

$= 99m²$

$therefore , \: area \: \\ of \: circle \: is \: 99m².$

$and, \: radius \: is \: \frac{693}{7} m.$
