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

Does anyone know the answer?

KatRina [158]

The nth term of the equation would be:

Tn=an+b
a=constant difference
b= term 0 (term before first term)

Tn=3n-30

A) 126=3n-30
n=52 (valid because it is positive)

B) 461=3n-30
n=163.67 (invalid because it is not a whole number and a position needs to be a whole number)

C) 657=3n-30
n= 229 (valid)

D) 501=3n-30
n= 177 (valid)

Your answer is B
