How Omega equals 2pai f?
imagine standing on a roundabout. f is the number of complete revolutions of the circumference which you make per second. omega on the other hand is the number of times you pass the radial distance per second. as the circumference of a circle is 2(pi)*radius, the number of times you travel a radius within a given time will be 2(pi) times the time to travel the circumference
The distance from Arcata to Crescent City is 86 miles A car was driven this distance using tires with a radius of 16 inches Approximately how many revolutions of each tire occurred on the trip?
Useful information: 86 miles tire radius of 16 inches In order to find how many revolutions the tire undertakes you must divide the amount traveld by the circumference of the tire (The length of tire tread). To find the circumference you multiply the diameter by Pi (3.14) The diameter is twice the radius or 32 inches 32 in. x 3.14 = 100.48 in. 86 miles equals 5,448,960 inches 5448960 in. /100.48 in. = 54229.3 revolutions
If a wagon wheel has a diameter of 70 centimeters how many revolutions would it take to travel 66 meters?
To figure out how long a revolution is you need to find the circumference of the wheel. If the diameter is 70 centimeters, then to get the circumference you multiply the diameter by pi (3.14). That equals 219.8. centimeters. Then you convert 66 meters into centimeters, and that is 6600. Then you divide 6600 by 219.8 and get 30 revolutions.
If radius equals 2.25meters what is the circumference?
If radius equals 2.25 meters the circumference is: 14.1 meters.
