Suppose we are going to have pizza for lunch again next week. Mdm Lam will be ordering 10 boxes of 6" Personal Pizza and 10 boxes of 12" Large Pizza. You can only choose to eat either three slices from a small pizza (6") or two slices from a large pizza (12").

Which option would you choose in order for you to eat more pizza? :) Yummy yummy!

Justify your answer with workings.

AREA OF SECTOR OF 6 PERSON PIZZA IS EQUAL TO =90/360 X 3.1 42 X 3 X 3 =7.0695- = 7.07cm (3 SIG)

Area of sector for 3 pieces of 6"pizza=7.07x3 =21.21=21.2cm(sig)\

12''large pizza=45/360x3.142x6x6=14.137=14.1cm(3 sig)

Area of sector for 2 pieces of 12 pizza=14.137x2=28.274=28.3cm(3 sig)

I will choose to eat 12 'large pizza. It is more larger to eat and make me more less hungry.It will also make us more appetizing to eat.
