(4 pi r^3) / 3
4 times 16.9 = 67.6 ( step 1 )
67.6^3 = <span>308915.776 ( step 2 )

The answer before pi is ( <span>102971.925333 * PI ^3 ) ( step 4 )
after PI is ( </span><span>323495.844152 ^ 3 )
i first multiplied the radius by 4 (step 1)
i then cubed the number from step 1 ( step 2 )
i divided the number from step two by three ( step 3)
i then multiplied by PI, but also gave an answer without multiplying ( step 4 )

Let x = your number.
5x = x^2 - 14. To figure out the number, we have to first subtract 5x from each side.
0 = x^2 - 5x - 14. Factor.
0 = (x - 7) (x + 2). Set both terms to 0.
(x - 7) = 0. Add 7 to each side.
x = 7. You're looking for the negative value so this isnt the right one.
Set the other term (x + 2) equal to 0
(x + 2) = 0. Subtract 2 from each side.
x = -2
The negative solution for your number is -2
