fist find volume of whole
find volue of golf ball
volume of sphere=4/3 times pi times r^3

diameter=2radius
divide 2
diameter/2=radius
12/2=6=radius

4/3 times 3.14 times 6^3=904.32

whole volume=904.32

volume of golve ball
4/3 times 3.14 times 2/2=4.18666
subtract

904.32-4.18666=900.133333

the asnwer is 900.13 in^3
