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>

gogolik [260]

Let width be x

  • Length=x+8

\\ \rm\longmapsto 2(x+x+8)=48

\\ \rm\longmapsto 2x+8=24

\\ \rm\longmapsto 2x=24-8=16

\\ \rm\longmapsto x=\dfrac{16}{2}=8

One in 100 tennis balls produced at a factory is defective. if you randomly select five tennis balls, what is the probability th
Alex73 [517]
You can tell this is a binomial distribution since there is specific failure or success (getting a defective is success, for example). 

X~B(5, 0.01)  

P(X≥1)= 1-P(X≤1) 
=1-(0.999)
=9.80×10⁴ probability of getting at least one that is defective. 

Hope I helped :)
