Answer:
5.9 ft
Explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
872 = 4/3 (3.14) r^3
872 =4.186666666 r^3
Divide each side by 4.1866666 on each side
872 / 4.186666666 = r^3
208.2802548 = r^3
Take the cube root of each side
(208.2802548)^(1/3) = r^3^(1/3)
5.927652012 = r
Rounding to the nearest tenth
5.9 ft
