$\bf radians = \cfrac{degrees \times \pi}{180}$

anonymous · Answer

That gives me -7.85? my answer which is - 5pie/2 correct?

anonymous · Answer

my answer choices are
-5pi/2
-5pi/4
5pi/2
-5pi

anonymous · Answer

im i correct? @jdoe0001

jdoe0001 · Answer

well, yes, -7.85 RADIANS, is correct
as far as your choices, your choices are in $\large \pi $ terms, so use the $\large \pi$ version without multiplying, just simplifying the fraction for that

anonymous · Answer

Im confused, what is the correct answer then?

anonymous · Answer

is the answer -5pi/2? because that equals -7.85

jdoe0001 · Answer

well, you were asked to multiply by $\boldsymbol{\pi}$ in the calculator and give a radian unit, so -7.85 radians is correct

but your choices are in $\pi$ terms, meaning you are not supposed to multiply by $\pi$ to match up any of the choices

jdoe0001 · Answer

so to match up any of those choices,  you'd need to simplify $\bf \cfrac{-450 \times \pi}{180}$

jdoe0001 · Answer

or $\boldsymbol{\cfrac{-450  \pi}{180}}$
