RADIAN TO DEGREES 1


Change 5∏/4 radians into degrees.

Solution

Ө = 1800 x s                but s = 5∏/4
       ∏

Ө = 1800  x  5∏              
       ∏     4

Ө =  45180  x  5∏ 1             
          1∏     41

= 45 x 5

= 135

Hence 5∏/4 radian is equal to 1350.

TRY THIS………………….


Change 7∏/6 radians into degrees.
