Answer:
78.54
Step-by-step explanation:
first you have to divided 31.4 by 3.14 to get your diameter so you can get your radius. 31.4 divided by 3.14 equals 10 and 10 divided by 2 equals 5 which is you radius. The formula for area for a circle is πr². 5 squared is 25 and 3.14 times 25 equals 78 .54 which is your answer.
the answer is -8. have a nice day!⭐️
<span>One nickel is 0.077 inches thick. Thus, a stack of nickels that is 100 inches tall would be composed of 100 divided by 0.077 nickels. So, a stack of nickels 100 inches tall would need 1299 nickels.</span>
Rewriting the equation of the given line in slope-intercept form,
![-x-4y=1\\\\-4y=x+1\\\\4y=-x-1\\\\y=-\frac{1}{4}x-\frac{1}{4}](https://tex.z-dn.net/?f=-x-4y%3D1%5C%5C%5C%5C-4y%3Dx%2B1%5C%5C%5C%5C4y%3D-x-1%5C%5C%5C%5Cy%3D-%5Cfrac%7B1%7D%7B4%7Dx-%5Cfrac%7B1%7D%7B4%7D)
From this, we know the slope of the given line is -1/4.
Since parallel lines have the same slope, we know the line whose equation we want to find has a slope of -1/4.
Substituting into point-slope form,
![y=-\frac{1}{4}(x+4)\\\\\boxed{y=-\frac{1}{4}x-1}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B1%7D%7B4%7D%28x%2B4%29%5C%5C%5C%5C%5Cboxed%7By%3D-%5Cfrac%7B1%7D%7B4%7Dx-1%7D)
