Question

change -54 degrees to radian measure in terms of pi

Answer 1

For example, if I want to convert \(\color{#000000 }{ \displaystyle 40^\circ }\) to radians, then I divide by 180 and multiply times \(\large\color{#000000 }{ \pi }\).

\(\large\color{#000000 }{ \displaystyle 40^\circ =40\times \pi \div 180 = 2\pi/9 \color{gray}{\rm~ rad} =0.69813 \color{gray}{\rm~ rad}}\)

Answer 2

i got 3pi/10 as my answer ; n ;

Answer 3

-54 degrees, that is in quadrant 4

Answer 4

just a sign change

Answer 5

yeah just remember a full circle is 2pi or 360

2pi rad = 360 deg

use that ratio to convert units

Answer 6

or pi/180 as above, same thing

Answer 7

or use any degree you want, just anything you know to get from rad to deg or back
