Given :-

  • Capacity (V) = 1 litre
  • Diameter (d) = 14cm

To Find:-

  • Height of the tin.

Solution:-

Formula used:-

  • V = πr²h

Here,

  • V = Capacity of cylindrical tin
  • r = radius of tin
  • h = height of tin

As we know,

★ 1 litre = 1000 cm³

•°• V = 1000cm³

According to the question;

→ V = πr²h

→ 1000 = 22/7 × (7)² × h

→ 1000 = 22/7 × 49 × h

→ 1000 = 22 × 7 × h

→ 1000 = 154 h

→ h = 1000/154

→ h = 500/77

→ h = 6.49 cm

Hence,

  • Height of the tin = 6.49 cm.
