Question

Why don't we put the value of π as 180° in the formula for radian, i.e., 1radian=180°÷π?​

Answer 1

Step-by-step explanation:

Think of it as solving proportions. We have

π radians=180∘

and you want to convert

r radians = d∘.

Hence you get

πr =180 d

which simplifies to

r = π 180 dor equivalently d=180πr.
