Volume of a sphere = (4/3)*(pi)*(r)^3 so:

(4/3)*(pi)*(8)^3 = 2144.66 cu. ft.

4/3 * pi * radius^3

radius = diameter/2

4/3 * pi * 8^3

4/3 * pi * r^3

so 4/3 *pi* 8 ^3 (512)

You can work out the rest

Vol. of sphere = (4/3) Ï rÂ³
....................= (4/3) (22/7) 8Â³
....................= 2145.5 c.ft
