Question

Which expression converts StartFraction pi Over 4 EndFraction radians to degrees?

Answer 1

Answer:

StartFraction pi Over 4 EndFraction times StartFraction 180 degrees Over pi EndFraction.

Step-by-step explanation:

We know the relation between radian and degree is that, π radians = 180°.

Then we have to calculate the degree that is equivalent to $\frac{\pi }{4}$ radians.

Now, using the unitary method, we can calculate the degree value.

Therefore, $\frac{\pi }{4}$ radians is equivalent to $\frac{\pi }{4} \times \frac{180}{\pi } = \frac{180}{4} = 45 ^{\circ}$.

So, it is StartFraction pi Over 4 EndFraction times StartFraction 180 degrees Over pi EndFraction. (Answer)
