Question

Convert –18° to radians

Answer 1

I think it will be 0.314 radian

Answer 2

-π/10 radians

Explanation:

To convert degrees to radians, the following conversion is used:

180° = πrad

To convert -18° to radians

Let -18° = x rad

Cross multiplying both equalities to find the unknown variable x we have;

180° × x = -18° × π

x = -18π/180°

x = -π/10radians

The conversion of -18° to radians is -π/10radians
