Answer 1

Answer:

2375 ft.

Step-by-step explanation:

Diameter = 2r

63 ft = 2r

31.5 ft = r

Distance traveled in one revolution is circumference, which equals 2πr.

12 revolutions * 2πr = 24πr = 24*31.5*π = 2375 ft.

Answer 2

Answer:

2373.84 feet.

Step-by-step explanation:

Diameter of the Ferris wheel = 63 feet

Radius of the Ferris wheel = r =  63/2 feet

Perimeter of the Ferris wheel = $\[2*\Pi *r\]$

$\[=2*\Pi *\frac{63}{2}\]$

$\[=197.82\]$

During 1 revolution, the rider travels 197.82 feet

When the Ferris wheel makes 12 revolutions, the rider travels [tex}\[197.82*12\][/tex] feet, that is 2373.84 feet.
