Question

How many turns needed for a rider to travel one mile on a Ferris wheel that is 250 feet in diameter and height of 264?

Answer 1

If you knew that if you go one turn on the wheel you travel 785.4 ft, can you figure out how many turns to go 5280 ft?
Use a ratio:
\[ \frac{1 \text{ turn}}{785.4 \text{ ft}} = \frac{x \text{ turns}}{5280\text{ ft}}\]

btw, you figure out the distance of one turn by using
\[ C= 2\pi r = \pi d \]
