How many different ways can 12 people line up to go to the same bathroom
Aneli [31]
There are 12! ways to line 12 people up.  That is 12 factorial (the name for the exclamation point
12! means 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

Using a scientific calculator to compute 12!, we get 479,001,600 ways to line up 12 people.  I know it sounds amazing but here is a chart.

People            Ways

3                       6
4                      24  (Notice that if you multiply 6 x 4 you get 24)
5                     120  (Notice that if you muliply 24 x 5 you get 120  etc.)
6                     720
7                     5040
8                    40,320
9                    362,880
10                 3,628,880
11               39,916,800

liubo4ka [24]

Answer:

10.5 squared centimetres.

Step-by-step explanation:

First, find the area of that sector. We are already given that the circle is 154 squared centimetres.

We are given 90 degrees (or one fourth of the circle). Thus, divide 154 by 4 to get the area of the sector (the white area).

The area of the sector is 154/4 or 38.5

We then need to find the area of the square. After that, we can subtract the sector area (the white area) from the area of the square (the total area) to find the area of the shaded section.

The area of the square is 7*7 or 49.

Thus, the shaded portion will be 49-38.5 or 10.5 squared centimetres.
