Answer:6.0002inch

Step-by-step explanation:

Volume of sphere=904.39

π=3.14

Volume of sphere=4/3 xπ x r^3

904.39=4/3 x 3.14 x r^3

904.39=(4x3.14xr^3) ➗ 3

904.39=(12.56xr^3) ➗ 3

Cross multiplying we get

904.39x3=12.56xr^3

2713.17=12.56xr^3

r^3=2713.17 ➗ 12.56

r^3=216.02

Taking the cube root of both sides

r=3√216.02

r=6.0002
