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.
