I assume you meant "a stone in the form of a sphere..."
The formula for the volume of a sphere is:
v+=+%284%2F3%29%2Api%2Ar%5E3
r+=+d%2F2+=+42%2F2+=+21+cm
v+=+%284%2F3%29%2Api%2A%2821%5E3%29
v+=+12348%2Api+=+38792.4 cubic centimeters. At 2 grams/cc, the stone would weigh 77584.8 grams, or 77.5848 kilograms
