Answer:
Hence diameter of the cylinder = 6 × 2 = 12cm
Step-by-step explanation:
Given height of the cylinder = 21cm
CSA (lateral surface area) of the cylinder = 792cm²
Therefore 2πrh = 792cm²
→ 2×22/7×r×21 = 792cm²
→ 44×r×3 = 792cm²
→ 132×r = 792cm²
→ r = 792/132
→ r = 6cm
Hence diameter of the cylinder = 6 × 2 = 12cm
