volume = 2.1958×10¹⁰ km³
⇒ 4/3 πr³ = 2.1958×10¹⁰
⇒ r³ = 2.1958×10¹⁰ ×π×3/4
⇒ r³ = 5.1711×10¹⁰ km³
⇒ r = ∛5.1711×10¹⁰
⇒ r = 3.7256 ×10³ km
To nearest tenth, radius = 3.7 ×10³ km
⇒ 4/3 πr³ = 2.1958×10¹⁰
⇒ r³ = 2.1958×10¹⁰ ×π×3/4
⇒ r³ = 5.1711×10¹⁰ km³
⇒ r = ∛5.1711×10¹⁰
⇒ r = 3.7256 ×10³ km
To nearest tenth, radius = 3.7 ×10³ km
