A soft- drink cup is in the shape of a right circular cone with a capacity of 250 millilitres. The radius of the circular base is five centimetres. How deep is the cup? (1 millilitre = 1 cubic centimetre). (Explain your answer).
The volume of a right circular cone is:
V = pi*r*r*h/3, where r is ...
The height of a cone is found, given radius and volume.
