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.

1. What have you learnt?

2. Share your thoughts on the above activity :)

Area of Sector for a 3 pieces of 6" pizza=90/360x3.142x3x3=7.0695 square cm

3 slices of 6" pizza = 7.0695 x 3 = 21.2085

=21.2 square cm ( 3 sig )

Angle for a piece of 12" pizza=360/8=45

Area of Sector for a 2 pieces of 12" pizza= 45/360x3.142x6x6=14.139 square cm

2 slices of 12" pizza = 14.139 x 2 = 28.278

= 28.3 square cm ( 3 sig )

I will choose to eat 2 slices of 12" pizza because it has a larger area of sector than the 3 slices of 6" pizza by 7.1 square cm.
