Remember that

the volume of teh sphere is equal to

[tex]V=\frac{4}{3}\cdot\pi\cdot r^3[/tex]

the volume of three golf balls is

[tex]\begin{gathered} V=3\cdot\lbrack\frac{4}{3}\cdot\pi\cdot r^3\rbrack \\ V=4\cdot\pi\cdot r^3\rbrack \end{gathered}[/tex]

we have

r=1.68/2=0.84 in

pi=3.14

substitute

V=4(3.14)(0.84^3)

V=7.44 in3

answer is 7.44 cubic inches
