here, i used paint, sorry if you couldn't understand it ; EDIT: forgot to put the unit ^3
Radius=Diameter / 2
Radius=8 / 2 =4
V=4/3.Pi.r^3
V=4/3.3.141592.4^3
V=268.08 Cubic units.
+206 The formula to find the volume of a sphere is V= 4/3 * TT * r3. Radius is half of the diameter so instead of 8 it is 4. Pi is a really long number so you can just use 3.14. Replace the "r" with 4. 4 cubed is 64. 64 * 3.14 = 200.96. Last, multiply 200.96 * 4/3 which will give you an answer of 267.9466666666666667. You can round this to the nearest hundred, ten, one, tenth, hundredth, or thousandth. I took pre-algebra in 8th grade so this is easy.
