Question

In TABLE 1 below is a list of explanations and definitions of concepts used in Mathematical Literacy.

TABLE 1: EXPLANATIONS AND DEFINITIONS OF CONCEPTS

A The distance from the centre of a circle to the outer part of the circle
B The use of cardinal directions (i.e. north, south, east, and west) to describe the location of one point to the other
C The path or boundary that surrounds a circular-shaped object or surface
D A position which is not exact, but roughly shows the location of an object
E A measure of body fat based on the height and weight of an adult person
F The total area of all the faces of a 3-D shaped object
G A special type of diagram used to determine the outcomes of an event in
H The arrangement of something laid out, such as the structural features of a 
I The ratio of the distance in real life compared to the same distance on a map
J The rate of covering a certain distance over time

Use the information above to write down the letter of the explanation or definition (A to J) of EACH of the following concepts:

1.1.1 BMI (body mass index)
1.1.2 Circumference
1.1.3 Map scale
1.1.4 Compass direction
1.1.5 Tree diagram

1.2 ANNEXURE A shows the layout of a vegetable garden with different plant beds, as well as TABLE 2 which shows plants with their partner plants.

Use ANNEXURE A to answer the questions that follow.

1.2.1 Identify THREE plants that have cabbage as a partner.
1.2.2 Determine the number of partners of the plant found in bed 4 of the vegetable garden.
1.2.3 Name the partner plant which appears four times in the partner column.
1.2.4 Give the compass direction of sage from the onions in the vegetable garden.
1.2.5 Some of the plant beds in the vegetable garden contain more than one type of plant. Write down the plant bed numbers of these plants.

1.3 The sketches below show a pedestal and a diagram of the pedestal with its dimensions. The pedestal can be used as a table, plant stand or as extra seating.

Use the information above to answer the questions that follow.

1.3.1 Choose a formula (A, B or C) below which can be used to calculate the total volume of the pedestal.

NOTE: In EACH formula, r = radius and h = height.

A Volume = (2 × π × r × h) + (2 × π × r²)
B Volume = (2 × π × r³) × h
C Volume = π × r² × h

1.3.2 Write down the unit of measurement for the volume of the pedestal using the given unit in the diagram.

1.3.3 Give the height of the pedestal to metres.
