### Inverse Proportion (Examples) Half-Lives of Elements

One approach to describing reaction rates is based on the time required for the concentration of a reactant to decrease to one-half its initial value. This period of time is called the half-life of the reaction, written as

### Area of Parallelogram & Trapezium

Watch the following examples. Each comes with a question and the explanation on how to solve the problem.

1. Pause the question. Read the diagram carefully and think what formula would help you to solve for the unknown.

2. Think how you would solve the problem - you may need to write down an equation in order to solve for the unknown.

3. Next, continue to watch the clip and listen to the explanation. Is this similar to what you have thought of? Look out for the presentation of the working.

### Relating Volume of CONE with Volume of CYLINDER

The volume of a cone fills up one-third of the volume of cylinder, i.e. we need three cones to fill up a cylinder.

### Investigating: Volume and Surface Area of Sphere

What's the relationship between the
