Question

PLEASE HELP!!!
Convert -450° from degrees to radians. Use the value of π found on a calculator and round answers to four decimal places, as needed.

Answer 1

I got -7.8539 but what is that in pi form?

Answer 2

just multiply -450 times \[\frac{ \pi }{ 180 }\] and reduce.

Answer 3

\[-450\times \frac{ \pi }{ 180 }=-\frac{ 5\pi }{ 2 }\]

Answer 4

That is your exact value. Then just use the decimal value for pi to get the approximation.

Answer 5

thank you so much!!!!!!
