Question

how do you fine rad with the calculator...3rad divided by 4...

Answer 1

rad meaning radians. Its different for each calc unfortunately but you can work it out for yourself because deg = \[degrees \times \frac{\pi}{180} = radians\]

Answer 2

there are 3.142 radians in PI which is 180 degrees

Answer 3

oh ok so explain how 18 degrees . rad over 180 degrees = 0.3 rad

Answer 4

3 radians has a value of \[3*\frac{180}{\pi}=171.887 degrees\] and i guess \[\frac{171.887}{4}=42.97175\]

Answer 5

\[18 \times \frac{\pi}{180} = 0.314\]

Answer 6

18 degrees is a 10th of 180 so it must be a tenth of pi

Answer 7

If you times your answer by 10 you will get PI back. see?

Answer 8

yes that makes sense...thks...
