Question

In the navy pier Ferris wheel in Chicago has a circle conference that is 50% of the circumference of the first Ferris wheel built in 1893.

a. What is the radius of the Navy pier Ferris wheel?

b. What was the radius of the first Ferris wheel?

c. The first Ferris wheel chuck nine minutes to make a complete revolution. How fast was the wheel moving?


C= 439. 6 feet

Answer 1

Assume that the "C=439.6" is the circumference of the navy pier wheel Find the radius 2%2Api%2Ar = 439.6 r = 439.6%2F%282%2Api%29 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 = 439.6%2F.56 f = 785 ft is the circumference of the 1st wheel Fin the radius r = 785%2F%282%2Api%29 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? 785%2F9 = 87.2 ft/sec is the speed of the 1st wheel
