A bowl is a hemisphere with radius 6 cm. Water fills two-fifths of the volume of the bowl.
The water is poured into a hollow cone. The depth of the water in the cone is 12 cm
Volume of a sphere = πr3 where r is the radius.
Volume of a cone = πr2 h where r is the radius and h is the perpendicular height
Work out the radius of the surface of the water in the cone.
