Question

How many radians is `254^o`?

Answer 1

4.433 radians

Explanation:

There are `360 °` in a full circle and this is the same `2pi` radians;

i.e `360 ° = 2pi` radians

so it is a simple ratio issue: `1 ° = (2pi)/360` radians
`:. 254 ° = 254 xx (2pi)/360` radians
`:. 254 ° = 127/90pi` radians
`:. 254 ° ~~ 4.433` radians
