Question

please help me :)
A Ferris wheel at a carnival has a diameter of 62 feet. Suppose it turns at a rate of 70 revolutions per hour.
(a) Find the angular speed of the wheel in radians per hour.
(b) Find the linear speed of a passenger in feet per minute.

Do not round any intermediate computations, and round your answer to the nearest whole number.

Answer 1

a- angler speed = 70 *2pie = 140*22/7 = 20*22 = 440 rad/hr

Answer 2

ok so how do i do b?

Answer 3

wait

Answer 4

ok thanks

Answer 5

each round circumference = pie * diameter = 22/7 * 62 = 195 ft
speed = 70 round/hr = 70 round / 60 minute = 7/6 round/ min
so speed = (7/6)*195 feet/min = 227 feet/min

Answer 6

yes!!! thank you, thank you!!! can you help me on another problem?

Answer 7

yes you r welcome

Answer 8

A ceiling fan has 19-inch blades (so the radius of the circular fan is
19 inches). Suppose the fan turns at a rate of 55 revolutions per minute.
(a) Find the angular speed of the fan in radians per minute.
(b) Find the linear speed of the tip of a blade in inches per minute.

Answer 9

a - anguler speed = pie *55 = (22/7)*55 = 173 rad/minute

Answer 10

b- each round = pie*diameter = (22/7)*19 = 60 inch
speed = 55 round/minute = 55*60 inch/minute = 3300 inch/minute
