Question

How do you find `47^@30'` in radians?

Answer 1

`47^@30'` is equal to `(19pi)/72=0.829` radians

Explanation:

As there are `60` minutes, writtten as `60'`, in each degree,

Therefore, `47^@30'=(47+30/60)^@=47.5^@`

Now as `180^@` is equal to `pi` radians

`1^@` is equal to `pi/180` radians

and `47.5^@` is equal to `pi/180xx47.5=(19pi)/72=0.829` radians
