- When 3 litres of oil is removed from an upright cylindrical can the levels falls by 10cm. Find the radius of the can.
. A solid cylinder of radius 4cm and 8cm is method down and recast into a solid cube. Find the side of eh cube.
- Water flows through a circular pipe of internal diameter 3cm at a speed of 10cm/s. If the pipe is full how much water flows from the pipe in minute.
- Calculate the total surface area of the combined one / cylinder hemisphere below.
Curved surface of slice
The figure below shows the frustum of a cone this is formed by cutting in two cones, Base radius 2/cm and height 20cm by a plane parallel to the base;
The top cone of diameter 2/cm and height 10cm is then removed
- Volume of the frustum
- The total surface area, including the two ends
