Need help please .The ares of the sector shown below is 59 yd^2 find the length of the radius. Round to the nearest whole number
Vinvika [58]

\textit{area of a sector of a circle}\\\\ A=\cfrac{\theta \pi r^2}{360} ~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ A=59\\ \theta =40 \end{cases}\implies 59=\cfrac{(40)\pi r^2}{360}\implies 59(360)=40\pi r^2 \\\\\\ \cfrac{59(360)}{40\pi }=r^2\implies \cfrac{531}{\pi }=r^2\implies \sqrt{\cfrac{531}{\pi }}=r\implies 13\approx r

Eliza is at least twice as old as her friend's younger sister, Wendy.
satela [25.4K]

Answer:

e ≥ 2w

Step-by-step explanation:

To make this easier, let us consider the case of Eliza being exactly twice as old as wendy

that would mean that twice the age of Wendy is the age of Eliza

e = 2w

but since she is AT LEAST twice as old as her, the age of eliza can be greater than twice of wendy and it might be equal to twice the age of Wendy

Hence, the symbol '=' will be replaced by '≥'

Hence, the correct relation is

e ≥ 2w
