Find the volume of the sphere. either enter an exact answer in terms of find the volume of π or use 3.14 for find the volume of the sphere. either enter an exact answer in terms π or use 3.14 for π and round your final answer to the nearest hundredth.

1436.03 units³

Step-by-step explanation:

The formula for the volume of a sphere of radius r is

V = (4/3)πr³.  We'll use 3.14 for π.

Then:

V = (4/3)(3.14)(7 units)³.  To the nearest hundredth:  1436.03 units³

Step-by-step explanation:

Given

r = 7

pi = 3.14

Formula

V = (4/3) pi * r^3

Solution

V = (4/3) * pi * 343

V = (1.3333) * 3.14 * 343

V = 1435.99 You are going to get a lot of variation in this question: Everything depends on what value you use for 4/3. I used 1.3333 but it does go on. I would try this yourself. Whatever you get, enter it.

You are better off using 3.14 than using pi. You are still going to have to problem of how to represent 4/3

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
