What is 5π4\frac{5\pi}{4} radians in degrees?

A225°

B180°

C240°

D360°

Answer:

A. 225°

Read Explanation:

To convert radians to degrees, use:

1 rad=180∘π1 \text{ rad} = \frac{180^\circ}{\pi}

So,


5π4×180∘π\frac{5\pi}{4} \times \frac{180^\circ}{\pi}

5π4×180π=5×1804=225∘\frac{5\pi}{4}\times\frac{180}{\pi}=\frac{5\times180}{4}=225^\circ

Therefore, the angle is 225°.
