A sphere has a volume of 7,234.56 units^3. Using 3.14 for pi, find the radius of the sphere.

r = 1728 units

Step-by-step explanation:

Volume of sphere:  V = (4/3)(pi)(r^3), were r is the radius.

Solving this for r^3, we get

      V                           V                          7234.56 units^3

= r^3 =   so that  

(4/3)(pi)                 (4/3)(3.14)                           4.19

Thus, r = 1728 units

answer: -1

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
