rerrange to find k so k=140 divided by (pi)
Soooo answer equals 44.6 to 1 d.p

So formula becomes 140° = k x 180°

Essentially, k = 140/180 = 7/9

Just make RHS in degrees or LHS in radians

8. I would say that 140 degrees is 7/18 of circle which in radians is 2π x 7/18 = 7π/9 radians. No need to memorise any formulas or anything.
