STUDY NOTES (p12): Application of Special Products

 

Below are examples that we discussed in class - you should have recorded them in your notebook.

Posting them here for your reference.

Unveiling the answers for ALGEBRA CHALLENGING QUESTIONS #1, #2, #3, #4

 

Class Practice (III) Our discussion on 24 APRIL

During the lesson, we looked at how (a) and (b) can be simplified using single fraction.

We learnt that while the approach could be different, both methods give the same answers (though they look different). We can also show how one answer is equivalent to the other.

For (c), the approach is similar to the following arithmetic example. When it is a product, we can expand the three factors in any order.

• 2 x 3 x 5 = (2 x 3) x 5 OR 2 x (3 x 5) OR (2 x 5) x 3

We discussed the following questions during lessons. 

Below are the suggested solution, showing how the working should be presented: 

 

SURFACE AREA of Sphere

Volume of Solids (non-Prism)

VOLUME of CONE


VOLUME of CYLINDER


VOLUME of SPHERE


RELATIONSHIP OF VOLUME of Cone, Sphere and Cube (think... what do they have in common?)

As mentioned in class this morning, the group will assign ONE Question to ONE MEMBER to post your worked solution in the Padlet. 

You will need to enter your name at the title of the post.
