5-5-6-6-6-8 The MEAN is the average.
The MEDIAN is the number in the middle.....if it is a list of an even number of terms (in this case six of them) , take the average of the middle two to be the median.... (6+6) /2 = 12/2 = 6 = median
Here is a good explanation of law of cosines: http://hyperphysics.phy-astr.gsu.edu/hbase/lcos.html
and here for law of sines

Agree with guest... this is likey the AREA OF A CIRCLE with a radius of 10
pi x r^2 = area of circle
Awful big topic to cover here...'.google' it or check out:

agree with HSC for this example, but I would add that if there are calculations inside the bars, you must do those FIRST before converting the contents to a positive
EXAMPLE | -3 -6| = + 9 NOT -3
Two vectors added together equal a 'resultant' ..the combo of the two component vectors.
Infinite answers to this.....when you have TWO unknowns (x and y) you must have TWO equations to reach a single discrete answer for x and y.
68/30 = 2 remainder 8
Slope is rise / run or (y2-y1) / (x2- x1)
Substituting:
slope = 1/4 = (2-y)/(4-6) = (2-y)/(-2)
1/4 (-2) = 2-y
-1/2 -2 = -y
5/2 = y
314159265359 / 100,000,000,000
A slightly different approach:
(28 1/4 - 9 1/2 ) / 2 = 9.375 " (9 3/8)
