The meaning of circumference is to find the distance around a circle or in other words the perimeter of the circle. The circumference of a circle can be calculate by using the formula
C=2πr or
C=πd, where r refers to the radius.
In this exercise is given a circle, which radius is 1 yard and it is asked to find its circumference and use 3.14 as the value of pi. In order to do that, you should substitute the given value of the radius and pi into the formula C=2πr.

The circumference of the circle is 6.28 yards.
The length of the pen is 8 meters and the width is 5 meters.
Explanation:
Since it is a rectangular goat pen the length and width can the the same number. So now just think of all the number that can be multiplied to get 40 and try them to see if they fit the perimeter too.
Say you get 8 and 5.
To check this you have to multiply the length times the width to see if it works for the area (which is 40 meters.
And 8 × 5 = 40, so these side lengths satisfy the area part... now to check if it works for the perimeter.
To find perimeter you add up all the sides. So if the length and width were to be 8 and 5 you would have to add up 8 + 8 + 5 + 5 To get the perimeter.
The total of 8 + 8 + 5 + 5 = 26 which satisfys the perimeter measurement.
So now you know the side lengths 8 (L) and 5 (W) work!
Answer: equation = $600 + tx$8 = $640 ; t = 5 additional hours in May
Step-by-step explanation:
Equation = $600 + tx$8/hour = $640
t = ($640 - $600)/$8/hour
t = $40/$8/hour = 5 hours
Answer: Equation = $600 + tx$8 = $640 ; t = 5 additional hours in May

The required equation of line is:
![y=-x+1](https://tex.z-dn.net/?f=y%3D-x%2B1)
Step-by-step explanation:
Given
m=-1
And point (2,-1)
The general form of slope intercept form of equation of line is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Putting the value of the slope
![y=-(1)(x)+b\\y=-x+b](https://tex.z-dn.net/?f=y%3D-%281%29%28x%29%2Bb%5C%5Cy%3D-x%2Bb)
To find the value of b, putting (2,-1) in the equation
![-1=-(2)+b\\-1=-2+b\\b = 2-1\\b=1](https://tex.z-dn.net/?f=-1%3D-%282%29%2Bb%5C%5C-1%3D-2%2Bb%5C%5Cb%20%3D%202-1%5C%5Cb%3D1)
Putting the values of b and m in equation
![y=-x+1](https://tex.z-dn.net/?f=y%3D-x%2B1)
The required equation of line is:
![y=-x+1](https://tex.z-dn.net/?f=y%3D-x%2B1)
