Question

How do you find, to the nearest minute, the angle whose measure is 3.45 radians?

Answer 1

`color(green)(3.45^c = 197^@ 40’`

Explanation:

Conversion of radians to degrees and degrees to radians is given by the formula

`D = (R / pi) * 180` where D = degrees, R = racism.

`D = (3.45 * 180) / pi = 197.67^@`

`1^@ = 60’`

Hence `0.67^@ = 0.67 * 60 = 40’`

`:.color(green)( 3.45^c = 197^@ 40’`
