The rock from a conical dump is to be used to metal a road to an average depth of 20cm throughout. The road is to be 7.0 m wide. If the diameter of the base of the dump is 80.0 m and the angle of repose of the waste rock is 37°, calculate the length of road which can be metalled by all the rock from the conical (10) dump. The area of the surface of the water in a reservoir is 10 830 m². During the month 6 366 100 litres of water is run out, the surface area being then 8 360 m². By what amount has the water being lowered? (10) The rock from a conical dump is to be used to metal a road to an average depth of 20cm throughout. The road is to be 7.0 m wide.
