Find the degree measure corresponding to the following radian measures (Use π =)

(i) (ii) - (iii) c (iv) (-3)c (v) 11c (vi) 1c

We know that π rad = 180° ⇒ 1 rad = 180°/ π


(i) Given



= (36 × 9) °


= 324°


(ii) Given



= (30 × -5) °


= -(150) °


(iii) Given



= (36 × 18) °


= 648°


(iv) Given (-3) c









= -(171° 49’ 5.45”)


≈ -(171° 49’ 5”)


(v) Given 11c




= (90 × 7) °


= 630°


(vi) Given 1c









= (57° 16’ 21.81”)


≈ (57° 16’ 22”)
