Find the arc length along a circle of radius 10 subtended by an angle of 215 degrees

natka813 [3]

Answer:

arc = 25.29

Step-by-step explanation:

first find the circumference:

C = 2r(Pi) = 2(10)(3.14) = 62.8

since subtended, then we're looking for these opposite angle of 215 degrees:

360 - 215 = 145 degrees

62.8/360 = 0.1744 per degree

0.1744 x 145 = 25.29

Answer:

$2.28*10^{3}\frac{mi}{h}$

Step-by-step explanation:

Let

x-----> the speed of sound in miles per hour

y----> the speed in Match 3

we know that

$y=3x$ -----> equation A

$x=7.6*10^{2}\frac{mi}{h}$

Substitute the value of x in the equation A

$y=3(7.6*10^{2}\frac{mi}{h})=22.8*10^{2}\frac{mi}{h}$

$22.8*10^{2}\frac{mi}{h}=2.28*10^{3}\frac{mi}{h}$
