Why do they call the math thingy pie?

A pie chart is so called because it is circular - like a pie - and parts or proportions of the total are represented by wedge shapes - like slices of a pie.


What is a pie diagram?

A pie diagram or pie chart is an illustration to show how information breaks down into categories. There are examples in the related links. Basically each wedge in a circle is drawn in proportion to the amount of the whole it represents. For example if a pie chart was drawn for a collection of coins where half the coins were dimes and 1/4 of the coins were pennies and 1/4 of the coins were nickels, the pie would be cut in half and then one of the halves cut in half again. Each piece would represent one type of coin.


Is a wedge like an inclined plane?

Yes a wedge is an incline plane.


Which has the greater mechanical advantage a wedge that is 6cm long and 3cm wide or a wedge that is 12cm long and 4cm wide explain?

To determine the mechanical advantage of a wedge, you can use the formula: Mechanical Advantage (MA) = Length of the wedge / Width of the wedge. For the first wedge (6cm long, 3cm wide), MA = 6/3 = 2. For the second wedge (12cm long, 4cm wide), MA = 12/4 = 3. Therefore, the second wedge has a greater mechanical advantage of 3 compared to the first wedge's mechanical advantage of 2.

To determine mechanical advantage (MA) of a wedge, we use the formula MA = length of the wedge / width of the wedge. For the first wedge, MA = 6 cm / 3 cm = 2. For the second wedge, MA = 12 cm / 4 cm = 3. Therefore, the second wedge (12 cm long and 4 cm wide) has a greater mechanical advantage of 3 compared to the first wedge's MA of 2.
