Question

A wheel has a radius of 15 cm. Approximately how far does it travel in 2 revolutions?

Answer 1

Answer and Step-by-step explanation:

$We~ require ~to ~calculate~ the ~circumference ~(C) ~of ~the ~wheel.$

$\boxed{Formula:C=2pi ~r}$

$Where~ r ~is ~the ~radius ~of ~the ~wheel.$

$We ~require~ 4 ~complete~ revolutions ~of ~the ~wheel.$

→ $Distance~traveled=2$ × $2pi~r$

$=2$ × $2pi~r$ × $15=60pi=188.49$

$=188.49$
