Oh, isn't that a lovely question! To get 180, you can multiply numbers like 18 and 10, or 36 and 5, or even 45 and 4. There are many combinations that can bring you to 180, just like the many happy little trees we can paint together.
Any (and every) number can be multiplied by 180.
First multiply 4 by 15 = 60, then multiply 60 by 3 = 180
20*-9 = -180 -180*21 = -3780 -3780*-1 = 3780.
1620 The easiest way to do this in your head is multiply 180 by 10 i.e. you add a "0" on the end so 1800, and then subtract 180 to give you 9 multiples of 180: 1800-180 = 1620
A full turn is 360° which is equivalent to 2π radians To convert form degrees to radians divided by 360° and multiply by 2π; however 360° = 180°×2, therefore divide by 180° and multiply by π radians. → 75° = 75° ÷ 180° × π radians = 5π/12 radians ≈ 1.31 radians
