Typo… 38…

Last Question of Paper 2:


(34-4)/2 = 17
1750cm100cm = 85 000cm3
85 000cm3+100^2cm3 = 95 000cm3 –> area of footpath
50cm/2 = 25cm –> radius of circle
(3.1425^238)cm3 = 74 575cm3 –> area of all circles (38 circles)
95 000cm3-74 575cm3 = 20425cm2 (a)

1750cm2 = 1700cm or 17m (b)

Hope this helps!




My DS says his answers seem like this too…
