Use the information above and answer the questions that follow. 2.1.1 What is the height of the part, in metre, of the container marked P if areas P and Q have the same height? (3) (3) 2.1.2 Determine the width and length of one rectangular lid. 2.1.3 Calculate the area, in mm², of one rectangular lid. You may use the following formula: (4) Area of a rectangle = length x width 2.1.4 Determine the volume in cm³, to the nearest 1 000, of the area marked A. You may use the following formula: (5) Volume of a rectangular prism = length x width x height 2.2 Cape Town stadium has one of the largest soccer fields in South Africa. The managers of the stadium want to replace the grass of the soccer field. Rectangular blocks of grass of 150 cm x 80 cm will be used to cover the soccer field. NOTE: Length of the soccer field = 110 meters Width of the soccer field = 80 yards Diameter of the circle in the centre of the soccer field = 14,64 metres 1 metre = 1,0936 yards 2.2.1 Determine the width (in m) of the soccer field. 2.2.2 Calculate the area of the grass in metres squared (m²) that needs to be replaced. The following formula may be used: Area = length x width 2.2.3 Calculate how many blocks of grass will be required to cover the soccer field. 2.2.4 Determine the radius of the circle in the centre of the soccer field. 2.2.5 Write down the letter that represents the correct formula that can be used to calculate the circumference of the circle: A C = 2tr² B C = Ar C C = 2nr

4 ft V=2 mrh 3 ft = 2T(4)(3) = 24 7 So, the volume of the cylinder ls 24 cublc feet. O The radius of the base should be doubled in the formula. O The height of the cylinder should be squared in the formula. O The radius of the base was used instead of the diameter of the base. The circumference of the base was used instead of the area of the base. Correct the error. Write your answer in terms of t. The volume of the cylinder is cubic feet.

A cubic block of cement is tossed into a cylindrical tank of water with a diameter of 2 feet, causing the water to rise 2.5 inches. Use the value of a from your calculator or n=3.1416. a.
