Answer:

\boxed{\boxed{\theta=150^{\circ}}}

Step-by-step explanation:

We know that,

\text{Arc length}=r\cdot \theta

where,

r = radius,

θ = central angle in radian.

Given,

diameter = 6 m, so radius = 3 m.

\text{Arc length}=\dfrac{5}{2}\pi

Putting the values,

\Rightarrow \dfrac{5}{2}\pi=3\theta

\Rightarrow \theta=\dfrac{5}{2\times 3}\pi

\Rightarrow \theta=\dfrac{5}{6}\pi=\dfrac{5}{6}\times 180^{\circ}=150^{\circ}

Arc length = (5/2) * PI meters = <span> <span> <span> 7.853981634 </span> </span> </span> meters
circle circumference = 2 * PI * radius = 2 *PI * 3
<span> <span> <span> 18.8495559215 </span> </span> </span>
arc length = (7.85381634 / <span> <span> 18.8495559215) * 360 = </span></span>

Which is a better state? <br> Ny or Florida <br> (Doing this for a statistic question)
Andrej [43]

Answer:

I would personally say Florida. When looking at things such as race, NYC has many races, and New York has very different neighborhoods and lifestyles.

In Florida, most people are more laid back, and there are not that many differences in race and other aspects.
