RADIAN INTO DEGREES 1


Change ∏/90 radians into degrees.

Solution

Ө = 1800 x s                but s = ∏/90
       ∏

Ө = 1800  x  ∏              
       ∏     90

Ө =  2 180   x   ∏ 1             
          1∏     901

Hence ∏/90 radian is equal to 20.

TRY THIS……………


Change ∏/20 radians into degrees.
