![r=4cm](https://tex.z-dn.net/?f=r%3D4cm)
Step-by-step explanation:
Having the radius to be involved, the shape is a circle.
<u>Circumference formula </u>
![c=2\pi r](https://tex.z-dn.net/?f=c%3D2%5Cpi%20r)
Finding radius, formula will be reversed.
![r=\frac{25.72cm}{2\pi }](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B25.72cm%7D%7B2%5Cpi%20%7D)
![r=4.09cm](https://tex.z-dn.net/?f=r%3D4.09cm)

Answer:
r = ±√47
Step-by-step explanation:
-7r^2 = -329 . . . . given
r^2 = 47 . . . . . divide both sides by -7 (multiplication property of equality)
r = ±√47 . . . . square root both sides (square root property of equality)
The answer to this question of yours is B
Answer: $97.524
Step-by-step explanation:
First let's calculate the price after the tax rate:
converting 7.50% to a decimal = 0.0750 now we multiply the sales tax by 75.60 which equals $5.67 add it to 75.60 = 81.27 (our new total)
Now let's calculate the tip. Again turning 20% to a decimal = .20 now multiplying by 81.27 = 16.254. Adding 16.254 to 81.27 we get our final answer: $97.524
