ANNEXURE B represents a South African map. Answer the questions below based on the annexure.

Here are the solutions to the problems:

4.1 Questions 4.1.1, 4.1.2, 4.1.3, and 4.1.4 require "ANNEXURE B", which is a South African map. This annexure is not provided in the image, so these questions cannot be answered.

4.2 This question requires the distance between Bloemfontein and Messina. This distance would typically be derived from a map (Annexure B, as suggested by question 4.1.3). Since the map is not provided, the distance is unknown, and therefore, the arrival time cannot be calculated.

4.3.1 Step 1: Identify the given dimensions and formula. The height of the tank is $h = 1200$ mm. The diameter of the tank is $d = 870$ mm. The formula for the volume of a cylinder is $V = 3.142 \times radius^2 \times \text{height}$.

Step 2: Calculate the radius from the diameter. The radius ($r$) is half of the diameter. $r = \frac{d}{2} = \frac{870 mm}{2} = 435 mm$

Step 3: Substitute the values into the volume formula. $V = 3.142 \times (435 mm)^2 \times 1200 mm$ $V = 3.142 \times 189225 mm^2 \times 1200 mm$

Step 4: Calculate the volume. $V = 3.142 \times 227070000 mm^3$ $V = 713453940 mm^3$ This calculated volume matches the volume given in the problem statement.

4.3.2 Step 1: Use the volume calculated in 4.3.1. The volume of the tank is $V = 713 453 940 mm^3$.

Step 2: Use the given conversion factor. 1 litre = 1 000 000 mm$^3$.

Step 3: Convert the volume from mm$^3$ to litres. $V_{litres} = \frac{713 453 940 mm^3}{1 000 000 mm^3/litre}$ $V_{litres} = 713.45394 litres$

Step 4: Round the answer to the nearest litre. $V_{litres} \approx 713 litres$ The volume of the tank in litres, rounded to the nearest litre, is $\boxed{713 litres}$.

4.3.3 Step 1: Identify the diameter of the tank. The diameter of the tank is $d = 870$ mm.

Step 2: Convert the diameter from millimeters (mm) to centimeters (cm). Since 1 cm = 10 mm: $d = \frac{870 mm}{10 mm/cm} = 87 cm$

Step 3: Convert the diameter from centimeters (cm) to inches. Given that 1 inch = 2.54 cm: $d_{inches} = \frac{87 cm}{2.54 cm/inch}$ $d_{inches} \approx 34.2519685 inches$

Step 4: Round the answer to two decimal places. $d_{inches} \approx 34.25 inches$ The diameter of the tank in inches, rounded to two decimal places, is $\boxed{34.25 inches}$.
