Sagot :

Answer:

1571 radians/minute

Step-by-step explanation:

A school bus tire with a diameter of 42 inches is rotating at a rate of 250 revolutions per minute. Find the angular speed of the tire in radians per minute. Round to the nearest tenth.

1 revolution = 2π radians

Hence:

Therefore, Angular speed =

250 revolutions /minutes × 2π radians/revolutions

= 1570.7963268 radians/ minutes

Approximately= the angular speed of the tire in radians per minute.

Therefore, the angular speed of the tire in radians per minute is the angular speed of the tire in radians per minute.
