Answer and Step-by-step explanation:

[tex]We~ require ~to ~calculate~ the ~circumference ~(C) ~of ~the ~wheel.[/tex]

[tex]\boxed{Formula:C=2pi ~r}[/tex]

[tex]Where~ r ~is ~the ~radius ~of ~the ~wheel.[/tex]

[tex]We ~require~ 4 ~complete~ revolutions ~of ~the ~wheel.[/tex]

→ [tex]Distance~traveled=2[/tex] × [tex]2pi~r[/tex]

[tex]=2[/tex] × [tex]2pi~r[/tex] × [tex]15=60pi=188.49[/tex]

[tex]=188.49[/tex]
