Diameter = 14cm
Given ,
- CSA of cylinder = 1320 cm²
- Height = 30cm
We need to find ,
- Diameter = ?
As we know that,
- CSA of cone = 2πrh
So ,
→ 2πrh = 1320
→ πrh = 1320/2
→ πr(30) = 660
→ πr = 660/30
→ πr = 22
→ r = 22/π
→ Radius = 7.0028 ≈ 7cm
Now ,
- Diameter = 2 × Radius
=> Diameter = 2 × 7
=> Diameter = 14cm
