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

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

What is the value of x?

vivado [14]

Answer:

x = 52/3

Step-by-step explanation:

3x / 7x = (3x+7) / (3x+7+5x-8)

3/7 = (3x+7)/(8x - 1)

Cross multiply

7(3x+7)=3(8x-1)

21x + 49 = 24x - 3

-3x = -52

x = 52/3
