Given,
- Volume of Cylinder = 2200cm³
- Height of Cylinder = 7cm
To Find,
- The CSA of Cylinder.
Solution,
Volume of Cylinder = 2200cm³ •••(given)
→ π × r² × h = 2200cm³
→ 22/7 × r² × 7cm = 2200cm³
→ 22cm × r² = 2200cm³
→ r² = 2200cm³/22cm
→ r² = 100cm²
→ r = 10cm
Required Answer,
CSA of Cylinder = 2 × π × r × h
→ CSA of Cylinder = 2 × 22/7 × 7cm × 7cm
→ CSA of Cylinder = 308cm²
