A Spherical water tank is to be constructed out of plastic materials. If the radius of the tank is 2 meters , and thickness of the water tank is to be 0.5 dm. What is the volume of the materials needed to construct the tank?

Study pp 21-29 of the Curriculum and Assessment Policy Statement (CAPS): Mathematics –

Intermediate Phase, which contains the Intermediate Phase overview for Space and Shape 

(Geometry) and Measurement. Thereafter, respond to the following questions:

1.1. Critically review the progression from Grade 4-6 for each of six topics under the content 

area, Space and Shape (Geometry). Write a short paragraph (three sentences) for each 

topic in which you discuss and motivate whether the progression provides a fair amount of 

cognitive and conceptual challenge at the relevant grade levels – too much, too little, or just 

right? (14) 

Sketch a counterexample showing that each statement is false:

1) Two triangles with three pairs of congruent angles must also have three pairs of congruent sides
