radius = 4.9 cm
volume = 4/3 πr³
volume of sphere = 4/3π x 4.9 x 4.9 4.9
= 493 cm³ ( nearly )
density = 7.8 cm
mass = volume x density
= 493 x 7.8
=3845.4 g
volume = 4/3 πr³
volume of sphere = 4/3π x 4.9 x 4.9 4.9

4\3 pie r3
4\3*22/7*4.9*4.9*4.9=493.00
density=mass\volume
mass=density*volume
493*7.8=3845.4 grms
4\3*22/7*4.9*4.9*4.9=493.00
density=mass\volume
mass=density*volume
493*7.8=3845.4 grms
