First we have to find the radius of the sphere because the circumference is 2*pi*radius.
4/3*pi*radius3 = 904.7786842 cubic cm
With your calculator multiply both sides by 3 and then divide both sides by 4*pi:
radius3 = 216
Cube root both sides:
radius = 6 cm
Circumference = 2*pi*6 = 37.69911184 or 38 cm to the nearest cm.

A sphere with this volume has a diameter of 9.1416 cm, a surface area of 262.54 square cm and a circumference of 28.719 cm.
A sphere with a radius of 7 inches has a volume of 1,436.76 cubic inches.
The formula is (4*pi/3)*r^3, so 256*pi/3 cubic units = 268.08 cubic units. {whatever units r is in}
Volume of a sphere = 4/3*pi*radius3 Volume = 2144.660585 cubic cm
113.1 cubic inches.
