Answer:

Step-by-step explanation:

The formula for arc length in terms of degrees is

A.L.=\frac{\theta}{360}*2\pi r and we have everything we need to fill in to find the angle measure.

123.53=\frac{\theta}{360}*56\pi which is the same as

123.53=\frac{56\pi \theta}{360} and

360(123.53)=56\pi \theta and

\frac{360(123.53)}{56\pi}=\theta so

θ = 253°

a circle with a radius of 3 has a sector with a central angle of 1/9 pi radians. What is the area of the sector?
Iteru [2.4K]

Answer:

The area of the sector is  \frac{\pi}{2}\ units^2

Step-by-step explanation:

step 1

Find the area of complete circle

A=\pi r^2

we have

r=3\ units

substitute

A=\pi 3^2

A=9\pi\ units^2

step 2

Find the area of the sector

we know that

The area of complete circle subtends a central angle of 2π radians

so

using proportion

Find out the area of a sector by a central angle of 1/9 pi radians

\frac{9\pi}{2\pi}=\frac{x}{\frac{1}{9}\pi} \\\\x=9\pi(\frac{1}{9}\pi})/2\pi\\\\x=\frac{\pi}{2}\ units^2

aniked [119]

Answer:

Richard will pay $30.

Step-by-step explanation:

Because "x" is equivalent to the amount of video games he rents, you would replace "x" with 5. Do the math, and you would get 10+20=30! Hope this helps!

I hope this helps!


g(x)= ax^2 + 24


g(4)= 8, g(-4)


a(4^2) + 24 = 8


16a+24= 8

-24 -24

16a = -16

a = -1
