h = 12 cm
l = 13 cm
r = √(l^2 - h^2) =√13^2 - 12^2 = √25 = 5cm
volume of cone = 1/3πr^2h = 1/3 × 3.14 × 5^2 × 12 = 314 cm^3
314cm^3 = 314ml = 314/1000 l = 0.314 litre
Capacity of cone is 0.314 litre
l = 13 cm
r = √(l^2 - h^2) =√13^2 - 12^2 = √25 = 5cm
volume of cone = 1/3πr^2h = 1/3 × 3.14 × 5^2 × 12 = 314 cm^3
314cm^3 = 314ml = 314/1000 l = 0.314 litre
Capacity of cone is 0.314 litre
