IF the navy pier ferris wheel in chicago has a circumference that is 56% of the
circunference of the first ferris wheel built in 1893.
:
a. What is the radius of the navy pier wheel?
Assume that the "C=439.6" is the circumference of the navy pier wheel
Find the radius
= 439.6
r =
r = 70 ft is the radius of the navy pier wheel
:
b. what was the radius of the first ferris wheel?
let f = circumference of the 1st wheel
.56f = 439.6
f =
f = 785 ft is the circumference of the 1st wheel
Fin the radius
r =
r = 125 ft is the radius of the 1st wheel
:
c. The first ferris wheel took nine minutes to make a complete revolution. how fast was the wheel moving?
= 87.2 ft/sec is the speed of the 1st wheel
