Calculate the total surface area in cm2of the paper that is needed to wrap the gift box.
You may use the following formula:
Total Surface Area of gift box = 2 (length × width) + 2 (width × height) + 2 (length × height) (4)
3.3
Electricity has become a scarce resource in South Africa. As a result, the country is investigating alternative sources of generating electricity. One alternative source of generating electricity is a wind turbine using rotating blades as shown in the picture and diagram below. Image of wind turbine Diagram of wind turbine The wind turbine is mounted on the top of a 50 m high tower. The length of each blade is 31 m. |
3.3.1 Determine the length of the diameter of the circle that the blades create as they rotate. (2)
3.3.2 Calculate the maximum height from the ground to the tip of a blade if the turbine is rotating. (2)
3.3.3 Calculate the circumference of the circle made by the blades when it rotates twice.
You may use the following formula:
Circumference = 2 × π × radius, using π = 3,142 (2)
3.3.4 Suppose each household requires 25 kWh of electricity daily.
If one wind turbine produces 1 750 kWh of electricity daily, calculate how many households could be provided with electricity daily from one such turbine. (2)
3.4 Sandra washes her dishes by hand three times daily in TWO identical cylindrical basins. She uses one basin for washing the dishes and the other for rinsing it. Each basin has a radius of 30 cm and a depth of 45 cm, as shown in the diagram below.
Cylindrical basin with dimensions Dimensions: Radius = 30 cm Height = 45 cm |
Sandra fills each basin to three quarters (¾) of its capacity whenever she washes or rinses the dishes.
Calculate how much water (in litres) she will use daily to wash and rinse dishes by hand. (NOTE: 1 000 cm3 = 1 litre)
You may use the following formula: Volume = π × r2 × h, use π = 3,142 (5) [36]
QUESTION 4
4.1
