Golf balls are sold in packages of three and made from a solid rubber material. The diameter of the golf ball is 1.68 inches. Approximately, what is the volume of all three golf balls?
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
