This week is week ten the second to last week of the term. In maths this week we have been working on finding the circumference of a circle. We had to find the radius from knowing the diameter and find the diameter from knowing the radius. To find the radius from the diameter you have to half the diameter and to find the diameter from the radius you have double the number.Then once you have found the number you times it by pi which is a never ending number. When we use pi we select the first three numbers which is 3.14. Here is a quick example: If the radius is 3.2 then what is the diameter? The diameter would be 6.4 which we then have to times by pi.
3.14
x 6.4
--------
20.096
That is your answer and how you find the circumference of a circle. I think I did well with my work and I found it quiet easy.
