Any knowledge appreciated. I have been supplied with the question(s) and answer(s), but I need the method using equations on how to achieve the answers.
1. Two Containers P and Q are similar.
The surface area of container P is 2000cm^2.
The surface area of container Q is 125cm^2.
The volume of container P is 4000cm^3.
Calculate the volume of container Q.
Answer: 62.5cm^3
-------------------------------------------------------
2. There is a light security system.
The system can detect movement inside a sector of a circle.
The radius of the circle is 24m.
The sector angle is 125º.
Calculate the area of the sector.
Answer: 628.32m^2
-------------------------------------------------------
3. A solid silver rod is in the shape of a cylinder of height 15cm.
The diameter of it's base is 8cm.
(a) Calculate the volume of the cylinder.
Answer: 753.98cm^3
The silver is melted down and re-cast as a solid cone of height 32cm. During this process none of the silver is lost.
(b) Calculate the radius of the circular base of the cone.
Answer: 4.74cm
