180˚ = `pi` radians
12˚ x `pi/180= (12pi)/180`
Therefore, now simplify `12/180` = `1/15`
This means that 12˚ = `pi/15` radians.
Use proportions to convert degrees to radians. 180 degrees is equal to `pi` radians, therefore:
where r is the angle in radians equivalent to 12 degrees.
Solve for r by multiplying both sides by `pi`:
Thus 12 degrees is equal to 0.2094 radians.
