2.1.1 Calculate:
(a)The missing value D (in mm) (3)
(b)The total length (in mm) of the exposed sides of the runway (3)
(c)The area (in m2) of the runway that needs to be covered with carpet
You may use the following formula: Area of a triangle = length x width (4)
(d) The length (in m) of the hall (3)
2.1.2 Harry, a British model, wants to know the measurement (in feet) of the front end of the runway.
Convert 4,2 m to feet, rounded off to one decimal place. NOTE: 1 foot = 0,3048 m (3)
2.2.1 Determine A, the length (in cm) of ONE side of the square base.
You may use the following formula: Volume of box with square base = (side)2 x height (4)
2.2.2 The organisers of the fashion show want to use their own label around the outer curved side of the cylindrical container. The label will be I cm longer than the circumference of the circular base to allow for an overlap.
Determine the total area (to the nearest cm2) of all the labels that will be required for 76 cylindrical containers.
You may use the following formula: Area of one label (in cm2) = [1 + 2 π x r] x height using π = 3,142 (4)
2.2.3 Show, with calculations, that the volume of the cylindrical container is 238,99 cm3 more than the volume of the container with the square base.
You may use the following formula: Volume of cylinder = π x r2 x height using π = 3,142 (3)
2.2.4 State the most appropriate metric unit of measure for the mass of a container of chocolates. (2)
