Answer:
510064471909788 m²
Explanation:
diameter=12742 so the radius r=12742/2=6371=6371*1000=6371000
A=4πr²
A=4π(6371000)²
A=162358564000000π =510064471909788 m²
510,064,471,910,000 m² or 5.1 x 10^14 m²
4πr²
if the diameter is 12742, then the radius is 6371
4π(6371)²
510,064,471.91 km²
510,064,471,910,000 m²
