Radius of Circle = 30 cm

To Find :-

Area of the Circle

Formula Used :-

area \: of \: circle \:  =  \: \pi \:  {r}^{2}

Solution :-

area \: of \: circle \:  =  \: \pi \:  {r}^{2}  \\  \\ r \:  =  \: 30 \: cm    \\ \pi = 3.14 \\  \\ area \:  =  \: 3.14 \times 30 \times 30 \\  \\ area \:  = 2826 \:  {cm}^{2}
