given that the value of circumference of a circle is 2/3 of its area. determine the length of the radius of the circle!​
sineoko [7]

\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}  }

<u>According</u><u> </u><u>to</u><u> </u><u>the question</u><u>, </u>

<em>circumference of a circle is 2/3 of its area.</em>

:\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

<u>Therefore</u><u>, </u><u>the length of the radius of the circle</u><u> </u><u>is</u><u> </u><em>3</em><em> </em><em>unit</em>

Help ASAP !!!!! Which number line represents the solutions to \x + 4) = 2?
Pachacha [2.7K]

Answer:

first option

Step-by-step explanation:

Given

| x + 4 | = 2

The absolute value function always produces a positive value but the expression inside can be positive or negative, thus

x + 4 = 2 ( subtract 4 from both sides )

x = - 2

OR

- (x + 4) = 2, distribute left side

- x - 4 = 2 ( add 4 to both sides )

- x = 6 ( multiply both sides by - 1 )

x = - 6

Thus solutions are x = - 2, x = - 6

These are represented on the graph by solid blue circles at x = - 2, x = - 6

The first option represents the solution
