Answer:

  V = (4/3)πr³

Step-by-step explanation:

The formula usually used to find the volume of a sphere is ...

  V=\dfrac{4}{3}\pi r^3

where r represents the radius of the sphere.

The actual math involved will depend on what information about the sphere you are given. If you are given the radius or diameter (twice the radius), then this formula will be directly useful.

Help me please FOR A GRADE ‼️ What is an equation of the line that is parallel to Y=4x-1 one and that passes through the point -
Sliva [168]

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0, or (0,y))


For lines to be parallel, their slopes have to be the SAME.


The given line's slope is 4, so the parallel line's slope is also 4.

y = 4x + b

To find "b", plug in the point (-3,5) into the equation.

y = 4x + b

5 = 4(-3) + b

5 = -12 + b    Add 12 on both sides

17 = b



y = 4x + 17
