Question

Convert:

(a) 215° 46’ 48” to grads

(b) 320.0648 grads to degrees, minutes, and seconds

(c) 151° 18’ 45” to radians.

Answer 1

(a) 215° 46’ 48” to grads

215+(46/60)+(48/3600)= 215.78 grads

(b) 320.0648 grads to degrees, minutes, and seconds

320.0648-320= 0.0648

0.0648*60= 3.888 minutes

3.888-3= 0.888

0.888*60=53.28 seconds

320° 03’ 53”

(c) 151° 18’ 45” to radians.

convert it to grads first

151.3125 grads

multiply by pi/180

2.6396 radians
