Question

the main rotor of a helicopter rotates 430 times per minute. find the number of degrees through which a point on the main rotor rotates in one second ​

Answer 1

2580 degrees rotated per second

Explanation:

since you have to find the degrees it rotates per second.

you need to divide 430 by 60 to find rotations per second

1) 430/60

= 7.16666667 rotations per second

-then you have to multiply it by 360 degrees ,because their is 360 degrees in a circle

2) 7.16666667 (360)

= 2580 degrees rotated per second
