Question

a ferrus wheel has a circumference of 89.49ft what is the approximately radius of the Ferris wheel? use 3.14 for pi

Answer 1

`\sf C=2\pi r`

Plug in what we know:


`\sf 89.49=2(3.14)r`

Simplify:


`\sf 89.49=6.28r`

Divide 6.28 to both sides:


`\sf r=\boxed{\sf 14.25\? ft}`

So the radius of the ferris wheel is 14.25 feet.
