the diagram below represents a drinking glass of diameter 10cm. it is partially filled to a height of hcm with apple juice.
(a) using 3.14 give an expression in term of h for the volume of juice.
the actual volume of the juice is 0.471 litres.
(b) calculate the value of h.( 1 litre = 1000 cm3

V = 3.14 * r^2 * h
Radius = 1/2 diameter
471 cm^3 = 3.14 * 5^2 * h
Solve for h.
