Question

3$\pi$ radians is equal to ________ degrees.

• A. 9.42
• B. 94.2
• C. 540
• D. 360

Answer 1

The correct option is C 540

We know that 2$\pi$ radians = 360${}^{\circ }$ for a circle
$\Rightarrow$ $\pi$ radians = $\frac{360}{2}$ = 180${}^{\circ }$
$\Rightarrow$ 3$\pi$ radians = 3$\times$180${}^{\circ }$ = 540${}^{\circ }$
