The Formula to find the Area of a circle using the radius is:

r = 8
So:



And you get about 201.06193
So, the area of a circle with a radius of 8 is about 201.06
Hope this Helps :)
Sin x = square root (2) / 2
In order for us to get for cos x and tan x, first we need to know what
Hypotenuse, Adjacent, and Opposite sides.
sin x = opposite / hypotenuse.
adjacent = square root (hypotenuse^2 - opposite^2)
adjacent = square root (2^2 - square root(2)^2)
adjacent = square root (4 - 2)
adjacent = square root (2)
cos x = adjacent / hypotenuse
tan x = opposite / adjacent..
cos x = square root (2) / 2
tan x = square root (2) / <span>square root (2) = 1
So, </span>cos x = square root (2) / 2 and tan x<span> = 1</span>

Step-by-step explanation:
<em>The question has mission options; However, the question is still solvable.</em>
Given


Required
Determine possible ordered pairs of A to B
A function is of the form (x,y)
Let A be the range of the function and B, the domain
Let (x,y) be a function of A to B, where x represents any of the values in A sets and y represents any of the values in B
A ordered pair can only be regarded as a function if and only if it has unique y-values
Hence, a possible ordered pair is:

Another possible ordered pair is

<em>Note that there as as many as possible ordered pair as long as the y-values are unique</em>
