The hard disk of a computer spins at 256 rotations per second. How many degrees does the hard disk pass through in one second?

Novay_Z [31]

One rotation means going once through a circular route.

One circular route means turning around by 360°

Now we know that one rotation always makes 360°.

The hard disk rotates 256 times in 1 second.

First we shall calculate the number of degrees.

In one rotation it covers 360°.

So in 256 rotations it covers 256 × 360 = 92160°

But these 256 rotations are made in one second.
