circumference \:  = 176 \\ \\ 2\pi \: r = 176 \\ 2 \times  \frac{22}{7} \times r = 176 \\ r = 176 \times  \frac{1}{2} \times  \frac{7}{22}  \\  r = 28 \\ area = \pi {r}^{2} \\  =  \frac{22}{7} \times 28 \times 28 \\  = 2464  \\ mark \: as \: brainliest

Circumference \: \: of \: \: circle = 2\pi r = 176 \: cm \\ \\ \\ r = \frac{176 \times 7}{2 \times 22} \\ r = \frac{1232}{44} = 28

Now,

 \: \: \: \: \: \: \: \: \: \: \: Area \: of \: circle = \pi {r}^{2} = \frac{22 \times {28}^{2} }{7} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{22 \times 784}{7} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 22 \times 112 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2464 \: {cm}^{2}
