The approximate radius of the sphere with volume of 998 cm³ is 6.2 cm
Volume of a sphere:
V = 4 / 3πr³
where
r = radius
V = 998 cm³
π = 3.14
V = 4 / 3 × 3.14 × r³
V = 12.56 r³ / 3
998 = 12.56 r³ / 3
cross multiply
998 × 3 = 12.56r³
2994 = 12.56r³
divide both sides by 12.56
r³ = 2994 / 12.56
r = ∛238.375796178
r = 6.20041444
r ≈ 6.2 cm
