Answer:

  30 units

Step-by-step explanation:

Make use of the formula for the volume of a sphere. Solve for the radius. (You can solve for the radius before or after you put the numbers in the formula.)

  V = (4/3)πr³

  36000π = 4/3πr³ . . . . put the numbers in the formula

  27000 = r³ . . . . . . . . . multiply both sides by 3/(4π)

  30 = r . . . . . . . . . . . . . .take the cube root

The radius of the sphere is 30 units.

the population of a country double every 10 years from 1950 to 1980.what was the percentage increase in population during this t
fredd [130]

700% increase.

Step-by-step explanation:

The duration was 3 decades, or 30 years. The population starts at 100%, then doubles to 200% (decade 1), then 400% (decade 2), then 800% (decade 3).

800% - 100% = 700%
