Step-by-step explanation:

circumference of circle = 2πr = 31.3 cm

2\pi \: r = 31.3 \\ 2 \times  \frac{22}{7}  \times r = 31.3  \\ r = 31.3 \times  \frac{7}{22}  \times  \frac{1}{2}  \\ r = 4.98cm

area of circle

\pi {r}^{2}   \\ =  \frac{22}{7}  \times  {(4.98)}^{2}  \\  =  \frac{22  \times  24.80}{7}  \\  = 22 \times 3.54 \\  = 77.9sqcm

hope you get your answer
