Cylindar?
a cylindar tent peg is driven into level ground. Later, it is removed by pulling it straight out. Describe the possible shapes of the top of the hole left by the tent peg at the surface of the ground. Explain how each of theses shapes is formed. use a diagram if necessary.

okay first of:confused: can you guys help me out here any help would be very appreciative thanks in advance!

Hello,

there are three different situations how a cylindrical peg could be placed:

1. perpendicular the ground. The shape of the top of the hole is a circle. The diameter of the hole is the same as the diameter of the peg.

2. The peg is driven in the ground under an angle between 0° and 90°. Than the shape of the hole is an ellipse.

3. The peg lies flat on the ground and is stamped into it. The shape will be a rectangle or because pegs mostly have a sharp point it is a rectangle with an additional triangle.
