Answer:

Step-by-step explanation:

Given the equation model 4x+(-4) = -2x+8

To find the value of x, the following steps must be followed

$4x+(-4) = -2x+8\\4x-4 = -2x+8\\subtracting\ 8\ from\ both\ sides\\4x-4-8=-2x+8-8\\4x-12=-2x\\4x+2x=12\\6x=12\\x=\frac{12}{6}\\ x = 2$

The value of x is 2

Point B is the center of the circle shown, and the length of arc AC is 8π. What is the area of the circle?

Gwar [14]

Answer:

$A=324\pi \text{ units}^2\approx1017.88\text{ units}^2$

Step-by-step explanation:

The formula for arc length is:

$\stackrel{\frown}{A}=2\pi r(\frac{\theta}{360}})$

Where Θ is measured in degrees.

We know that the arc length is 8π when the degree is 80. So, substitute 8π for A and 80 for Θ:

$8\pi=2\pi r(\frac{80}{360})$

Divide both sides by 2π:

$4=r\frac{80}{360}$

Simplify the fraction:

$4=\frac{2}{9}r$

Multiply both sides by 9/2:

$r=18$

So, the radius is 18.

Now, we can find the area of the circle. The formula for the area of a circle is:

$A=\pi r^2$

Substitute 18 into r:

$A=\pi (18)^2$

Simplify:

$A=324\pi \text{ units}^2\approx1017.88\text{ units}^2$

And we're done!
