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`
