Question

Convert -270 to radian measure.

Answer 1

Degrees to radians -
\[degrees*\frac{ \pi }{ 180 }\]

Answer 2

-270 degrees, right?

Answer 3

\[180^{o} = \pi^c\] this is the conversion rule , now you can use unitary method to find your answer.
if 180 degrees = 22/7 radians
1 degree = (22/7) / 180
270 degrees = 270* {(22/7) / 180]

Answer 4

270 degrees is three fourths of a circle. In radians, the circle is 2pi. Three fourths of that is 3pi/2. The opposite of that (measuring clockwise) would be -3pi/2.

Answer 5

Radian measures are almost always given in multiples of pi.

Answer 6

So the final answer would be -3pi/2?

Answer 7

yes

Answer 8

$$\frac{-3\pi}{2}$$
