Correct Answer - Option 2 : 12

**Given:**

Diameter of cylinder = 32cm

Height of cylinder = 9cm

**Formula:**

Volume of cylinder = πr^{2}h

Volume of sphere = 4/3 × πr^{3}

**Calculation:**

Radius of cylinder = 32/2 = 16cm

Volume of cylinder = 22/7 × 16^{2} × 9 = 2304π cm^{3}

Volume of sphere = 2304π cm^{3}

Then,

⇒ 2304π = 4/3 × πr^{3}

⇒ r = 12

**∴ Radius of sphere is 12cm.**
