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.
