Question

change -54 degrees to radian measure in terms of pi

Answer 1

To convert from degrees to radians you multiply by pi/180

\[\large -54 \times \frac{\pi}{180}\]

and then simplify

Answer 2

i tried -54(pi/180 and got 1?

Answer 3

-0.942477796076938?

Answer 4

in terms of pi, means you dont convert it to 3.14...

Answer 5

So like this...

\[\large -54 \times \frac{\pi}{180} = \frac{-54\pi}{180}\]

You would just simplify...not evaluate

Answer 6

you reduce what you can in the numerator and denominator (the constants of (-54pi/180)

Answer 7

oh ok so just reduce 54 and 180?

Answer 8

indeed

Answer 9

Right...so what would it reduce to?

Answer 10

\(\bf radians = \cfrac{degrees\cdot \pi}{180}\)

Answer 11

-5pi/12?

Answer 12

\(\bf \cfrac{-54}{180}\ne \cfrac{5}{12}\)

Answer 13

-3pi/10?

Answer 14

There we go!

Answer 15

\(\bf \cfrac{-54}{180}\ne \cfrac{-5}{12}\) rather

Answer 16

thank you not sure who to give the medal you all helped.
