It’s important to always check your mode. For scientific calculators, check the DRG button (Deg Rad Grad) to make sure it is in the correct mode. For TI calculators, press mode, and check if it is radians or degrees. The º symbol will tell you it’s a degree problem. Otherwise, it is likely a radians problem unless labeled otherwise. Radians Degrees

If a ferris wheel has 4 revolutions every 3 minutes, what is it’s angular speed in rad\sec If the wheel of a car has angular speed 80 revolutions per minute, and has a tire diameter of 2 feet, what is the linear speed in miles per hour? (round to hundredth) Given that pizza has a linear speed of 35 feet per second and has a radius of 10 inches, find the angular speed in revolutions per minute. Round to the nearest 100 th

I’m not really going to make a slide on these. These are the formulas. Theta represents angle measure. You just need to use the correct formula, plug them in, and you should be fine. The thing to watch out for is to see if they say it’s a radius or diameter, and apply the formulas correctly.
