Well , it is a diagram and that diagram is named Venn : )

A Venn diagram is an illustration that uses circles to show the relationships among things or finite groups of things. Circles that overlap have a commonality while circles that do not overlap do not share those traits. Venn diagrams help to visually represent the similarities and differences between two concepts.

Mostly used for set theory of mathematics.

From a to D which graph represents a function ? And why ?

tatiyna

Option D I believe because it is the only one that passes the vertical line test (the test that for every X value, there is only 1 Y value).

How do you solve this problem?

motikmotik

The arcs $AB, BC, AC$ all equal to the third of the perimeter since equilateral triangle divides them like this.

So we need to find a perimeter but we are only given the area.

Let's review,

$A=\pi r^2 \\P=2\pi r$

That means that from area we area able to calculate radius.

$A=\pi r^2\Longrightarrow r=\sqrt{\dfrac{A}{\pi}}$

Insert the numbers,

$r=\sqrt{\dfrac{36\pi}{\pi}}=6$

Then use the perimeter formula to calculate perimeter since radius is known,

$P=2\pi\cdot6=12\pi$

Now divide perimeter by 3 to get length of AB arc.

$AB=\dfrac{12\pi}{3}=\boxed{4\pi}$

Hope this helps.
