Question

Express the following circular measure as sexagesimal measure and centesimal system I 2pi c​

Answer 1

Answer:

(i)We know that 180∘=πc

⇒135∘=180∘135∘×πc

               =180135×722 where π=722

               =3627×722=1433c=2.356194radians

We know that 400gradian =360∘

⇒135∘=400135×360∘=121.5 gradians

(ii)We know that 180∘=πc

⇒270∘=180∘270∘×πc

               =
