Question

Which expression converts 45° to radians?

Answer 1

Answer

Find out which expression converts 45° to radians .

To prove

Relationship between degree to radians is given by

$1^{\circ} = \frac{\pi} {180}\ radian$

Now convert 45° to radians .

$=45\times\frac{\pi} {180}$

This the expression converts 45° to radians .

solving the above

$=\frac{\pi} {4}$

Put

$\pi = 3.14$

Put in the above equation

$= 0.785\ radians$

Hence proved

Answer 2

Degrees can be converted by doing $\frac{ \pi }{180} *degree measure$. Therefore, we can do $45* \frac{ \pi }{180}$, which is 0.7853 (approximately).
