An object is spinning around a circle at a rate of 420 revolutions per minute. If the circle has a diameter of 8 feet, what is its angular speed in degrees per minute. Do not add the units into your answer.

Step-by-step explanation:

This seems more like a physics questions, but i'll help you  :P

the circle is 8 feet across or a radius of 4 feet

circumference of the circle is 2r  = 25.132741 feet

it's going around 420 times a minute

420 * 25.132741 = 10555.75132 feet per minute

10,555.75
