V = PI x r^2 x H

471 = 3.14 x 5 x H
471 = 15.7 x h

h = 471 / 15.7 = 30 cm

314/ 15.7 = 20 cm

30-20 = 10 cm difference

Given the data below are the number of students in each age group.
nadya68 [22]
A scale of 1:50 000 means that every centimetre on the map is equal to 50 000 centimetres (500 metres) in reality.

The distance between two towns on that map is 6cm, therefore in reality there’s 6 * 50 000 = 300 000 centimetres, which is equal to 3 000 metres, which is equal to 3 kilometres.
