1) $6*12*4 - 4*4*4 = 4*(6*12-4*4) = 4*56=224m^2$

2) $6*6*6+\frac{8*6*6}{3}=312ft^2$

3) $3^2\pi(\frac{8}{3}+8) = \frac{9*8*4\pi}{3} = 96\pi m^2$

Step-by-step explanation:

GIven data

Felix's washing machine uses 6 gallons of water

we are told that A gallon is approximately 3.79 liters

Hence if a gallon is approximately 3.79 liters

then 6 gallons of water will be x liters

cross multiply we have

x= 6*3.79

x= 22.74 liters

Hence 6 gallon will be 22.74 liters

1. Parallelogram WXYZ is shown on the coordinate plane ect... Added photo plz help!!

aliya0001 [1]

Answer:

Step-by-step explanation:

12.718 units

Step-by-step explanation:

The coordinates of the vertices of parallelogram WXYZ are given to be W(0,-1), X(4,0), Y(3,-2) and Z(-1,-3).

So, the perimeter of the parallelogram will be 2(WX + XY) {Since opposite sides of parallelogram are same in length}

Now, length of WX = units, To find the units click this link :

https://tex.z-dn.net/?f=%5Csqrt%7B(-1)%5E%7B2%7D%20%2B%204%5E%7B2%7D%20%7D%20%3D%20%5Csqrt%7B17%7D%20%3D%204.123

And, length of XY = units, To find the units click this link :

https://tex.z-dn.net/?f=%5Csqrt%7B(4-3)%5E%7B2%7D%20%2B%20(0-(-2))%5E%7B2%7D%7D%20%3D%20%5Csqrt%7B5%7D%20%3D%202.236

Therefore, the perimeter of the parallelogram WXYZ = 2(4.123 + 2.236) = 12.718 units. (Answer)
