How long is the arc intersected by a 2pi/3 radian central angle in a circle with radius 7 feet?

VashaNatasha [74]

$=\frac{43.96}{3}$ Formula to find the central angle is,

$s= r\theta$

Where, s = arc length

r = radius

$\theta$ = central angle in radian.

According to the given problem,

r = 7 and $\theta = \frac{2\pi}{3}$ .

First step is to plug in these values in the above formula. So,

$s= 7*\frac{2\pi}{3}$

$=\frac{14\pi}{3}$ By simplifying.

$=\frac{14*3.14}{3}$ Since $\pi =3.14$

$=\frac{14*3.14}{3}$

s=14.65

Hence, arc length iss 14.65 feet.

Y= - x+2 Y=3x-4<br> Estimate the solution to the system of equations

IrinaVladis [17]

Answer:

$x=\frac{3}{2}\\ y=\frac{1}{2}$

Step-by-step explanation:

$y=-x+2\\y=3x-4$

Let's solve one of them for x.

$y=3x-4$

Add 4

$y+4=3x$

Divide by 3.

$x=\frac{y+4}{3}$

Now, plug the value of y in the formula, or you can plug the value of x in the other equation. I'll take this one.

$x=\frac{y+4}{3}$

$x=\frac{(-x+2)+4}{3}$

$x=\frac{-x+2+4}{3}$

$x=\frac{-x+6}{3}$

Multiply by 3 to get rid of the denominator.

$3x=-x+6$

add x

$3x+x=6$

Combine like terms;

$4x=6$

Divide by 4.

$x=\frac{6}{4}$

Simplify.

$x=\frac{3}{2}$

Now that you found the value of x, replace it in any of the equations to find y.

$y=-x+2\\y=-(\frac{3}{2})+2\\ y=-\frac{3}{2}+2$

$y=\frac{-3+2*2}{2} \\y=\frac{-3+4}{2} \\y=\frac{1}{2}$

Proof:

$y=3x-4\\\frac{1}{2}=3(\frac{3}{2})-4\\\frac{1}{2}=(\frac{9}{2})-4$

$\frac{1}{2}=\frac{9-4*2}{2}$

$\frac{1}{2}=\frac{9-8}{2}$

$\frac{1}{2}=\frac{1}{2}$
