Do what it says on the picture

D - 8

Step-by-step explanation:

V= 4/3 x pie x radius to the 3rd power

V = 4/3 x 3.14 x 1.25 to the 3rd power

V = 4/3 x 3.14 x 1.953125

V = 4.18666666667 x  1.953125

V = 8.17708333333

Rounded is 8

Option D, 8  

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

answer: 4 (:
