Surface area of sphere = 324 π
4πR² = 324π
4R² = 324π/π
4R² = 324
R² = 324/4
R² = 81
R = √81
R = 9 cm.
Radius of sphere ( R ) = 9 cm.
Therefore,
Diameter of sphere ( D ) = 2 × Radius = 2 × 9 = 18 cm.
4πR² = 324π
4R² = 324π/π
4R² = 324
R² = 324/4
R² = 81
R = √81
R = 9 cm.
Radius of sphere ( R ) = 9 cm.
Therefore,
Diameter of sphere ( D ) = 2 × Radius = 2 × 9 = 18 cm.

Answer:18cm
Step-by-step explanation:
Surface area of sphere = 324 π
4πR² = 324π
4R² = 324π/π
4R² = 324
R² = 324/4
R² = 81
R = √81
R = 9 cm.
Radius of sphere ( R ) = 9 cm.
Therefore,
Diameter of sphere ( D ) = 2 × Radius = 2 × 9 = 18 cm.
