Answer 2

Answer: 12474 $cm^{2}$

Step-by-step explanation:

Area for surface of a circle = $\pi r^{2}$  ( r = radius )

Area = 22/7 x 63 x 63 ( we say 63 twice as it is the formula. Which is r square so it  is 63 square and so on to get the area of a circle )

After cancellation-

=22 x 9 x 63 ( 7 and 63 get cancelled to form the 9 )

=22 x 567 ( we multiplied the 9 and 63 to make the equation simpler )

=12474 $cm^{2}$

Hence, the final answer is 12474 $cm^{2}$
