Twelve programmes aimed at giving direct help to all those having difficulty with 0-level maths. 7: Similarity
Problem: In a restaurant a carafe of wine costs £4.00 - how much should you pay for a similar carafe which is half the height? The answer is not E2.00. To get the right answer two things need to be understood. First, the precise mathematical definition of similarity. Second, the relationship between the scale factors of length, area and volume.
