What is the area of a stone wheel radius 63cm?

The area ( A ) of a circle is calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius. For a stone wheel with a radius of 63 cm, the area would be ( A = \pi (63^2) ). This calculates to approximately ( A \approx 3.14 \times 3969 \approx 12469.56 ) cm². Thus, the area of the stone wheel is approximately 12469.56 cm².
