<span>The arc length is 8</span>π.
The circumference of the circle is 2πr = 9<span>π.
</span>
so ![\frac{8 \pi }{9 \pi } = \frac{x}{360}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%20%5Cpi%20%7D%7B9%20%5Cpi%20%7D%20%3D%20%5Cfrac%7Bx%7D%7B360%7D%20)
cross-multiply: 9x = 360(8)
x = 320
The answer is D. because 10*10*10*10 = 10000, which also equals 10^4, which is repeated multiplication
Answer:
B = 64° , C = 26°
Step-by-step explanation:
2x+x-6+90 =180
3x + 84 = 180
3x = 180 - 84
3x = 96
x = 32°
B = 2x
B = 2 * 32
B = 64°
C = x - 6
C = 32 - 6
C = 26°
Answer:
![8x^2 + 18x + 36](https://tex.z-dn.net/?f=8x%5E2%20%2B%2018x%20%2B%2036)
Step-by-step explanation:
I did it on paper.
