given that the value of circumference of a circle is 2/3 of its area. determine the length of the radius of the circle!

$\boxed{\large{\bold{\textbf{\textsf{{\color{blue}{Answer}}}}}}:)}$

Let's assume the redius of the given circle is (r).

so,

circumference = $\sf{ 2\pi r }$
Area = $\sf{ \pi r^{2} }$

According to the question, 

circumference of a circle is 2/3 of its area.

$:\implies \dfrac{2}{3}×Area=circumference\\\\:\implies \dfrac{2}{3}×\pi r^{2}=2\pi r\\\\:\implies \pi r^{2}=2\pi r×\dfrac{3}{2}\\\\:\implies \pi r^{2}=3\pi r\\\\:\implies 3=\dfrac{\pi r^{2}}{\pi r}\\\\ :\dashrightarrow r=3$

Therefore, the length of the radius of the circle is 3 unit

Answer by JKismyhusbandbae: So this is really simple. You are probably making this out harder than it needs to be. Consider the set of ordered pairs {(-1,0), (4,-5), (6,-6), (9,11), (10,14)}. This set of ordered pairs is a function because for each value of x there is one and only one y-value. This means that the x value never repeats. Therefore any function is a function when the x value never repeats.

Looking at the table we want to find all it's ordered pairs: (0,4), (1,2), (2,3), (3,9), (4,1).

F(2) is 3 so when x equals 2.

So the ordered pair is (2,3) 2 is the x value and the f(2) is 3.
