Hi everyone,

I suspect Q10 from ACS PSLE 2012 prelim science paper is set wrongly.
If anyone experiencing the same and managed to get the right answers, pls pass it on.
Thnx.

I cannot do the questions on adaptations , can you post questions more on that particular topic?

1/2 X pi X 3 X 3 = 4.5 pi
8 / 2 = 4
1/2 X pi X 4 X 4 = 8 pi
8 pi + 4.5 pi = 12.5 p


ANSWER: 12.5 pi cm2
