Volume of a sphere using 3.14 for pi with a diameter of 28

11488.21 cm³

Step-by-step explanation:

The formula for the volume of a sphere is

The diameter is 28; this means the radius is 28/2 = 14.  Using 3.14 for π, we have

V = 4/3(3.14)(14³) = 11488.21

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. : )
