Answer by Cromlix(4381) (Show Source): You can put this solution on YOUR website!
Volume of a sphere = 4/3 pi r^3
3000 = 4/3 pi r^3
3000/4/3*pi = r^3
716.2 = r^3
r = cube root of 716.2 = 8.95 (2 decimal places)

VOLUME OF A SPHERE 4/3 PI ^3
3000=4/3PI R^3
3000/4/3*PI=R^3
716.2=R^3
R=716.2===8.95
(1)MULTIPLY THE VOLUME BY 3
(2)DIVIDE THE ANSWER IN (1) BY 3 PI THAT WILL GIVE YOU THE QUOTIENT
(3)CALCULATE THE CUBE ROOT OF (2)
