Use the following equation for the volume of a sphere:
V represents the total volume, and r represents the radius of the sphere.
Plug in your value for the radius.
The equation should now look like this:
Multiply 1000 by 4/3.
In terms of pi, the volume is
1333.33π cubic feet.
Assuming pi = 3.14, convert the symbol into the decimal, and multiply by 1333.33.
Rounded to the nearest whole number, the volume of the sphere is
4187 cubic feet.
