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
