Question

Convert the radian measure to degree measure. Use the value of π found on a calculator and round answers to two decimal places.
9pi/12

Answer 1

HI!!

Answer 2

you do not need a calculator for this, very misleading question

Answer 3

multiply by \(180\) and get rid of the \(\pi\)
the math teachers say "divide by \(\pi\) but that means it goes away

Answer 4

i.e. it is just \[\frac{9}{12}\times 180\]

Answer 5

also no one writes \(\frac{9}{12}\) when you can just write \(\frac{3}{4}\)

where does this question come from?

Answer 6

why do you multiply by 180?

Answer 7

lol my guess is FLVS

Answer 8

that is a good question

Answer 9

yes lol

Answer 10

and i get 135

Answer 11

to convert from degrees to radians, you multiply by \(\frac{180}{\pi}\)
the \(\pi\)'s cancel if you have one so it is really like multiplying by \(180\)

Answer 12

oh ok

Answer 13

and erasing the \(\pi\)
the explanation is easy

Answer 14

there are \(360\) degrees in the circle
measured in radians that is \(2\pi\) so to convert, multiply by \(\frac{360}{2\pi}=\frac{180}{\pi}\)

Answer 15

is it really FLVS?

Answer 16

yes y

Answer 17

i get a huge number. i think im lost

Answer 18

goes right in the "bad math" pile
most of the entries are from FLVS

Answer 19

no, you got the right answer

Answer 20

1279100.73???

Answer 21

you said you got \(135^\circ\) right?

Answer 22

\[\frac{3}{4}\times 180=135\]

Answer 23

no. where did that equation misty said come from with pi in it twice

Answer 24

your radian measure is \[\frac{3\pi}{4}\] to convert to degrees \[\frac{3\pi}{4}\times \frac{180}{\pi}=\frac{3}{4}\times 180=135\]

Answer 25

the \(\pi\)'s cancel
that is why the instructions are so misleading
you do not need to compute anything with the \(\pi\)
