Emily and her family are planning to fly to Italy over the summer. If they fly out from LAX, the distance of the trip will be 6,

Iteru [2.4K]

The speed is the ratio between the distance and the time:

$s=\frac{d}{t}$

Data:

d=6343miles

t=9h

$s=\frac{6343\text{miles}}{9h}=704.77\frac{miles}{h}$ Then, the plane traveled at a speed of 704.77 miles per hour.

An arc subtends a central angle measuring \dfrac{\pi}{2}

Agata [3.3K]

Arc Length is 1/4th of the circumference .

<u>Step-by-step explanation:</u>

Here we need to find fraction of the circumference is this arc when An arc subtends a central angle measuring $\dfrac{\pi}{2}$ radians ! Let's find out :

We know that circumference of an arc subtending a central angle of x is :

⇒ $Arc = \frac{Angle}{360}(2\pi r)$

⇒ $Arc = \dfrac{\frac{\pi}{2}}{360}(2\pi r)$

⇒ $Arc = \frac{90}{360}(2\pi r)$

⇒ $Arc = \frac{90}{90(4)}(2\pi r)$

⇒ $Arc = \frac{1}{4}(2\pi r)$

⇒ $Arc = \frac{1}{4}(Circumference)$

Therefore , Arc Length is 1/4th of the circumference .
