Question

How do you convert ${{570}^{\circ }}$ to radians?

Answer 1

Hint: We describe the relation between the degree and radians, two ways to express the angles. We find the relation that 180 degree is equal to $\pi $ radian. We express the radian value of ${{570}^{\circ }}$. We use the concept of unitary system.

Complete step-by-step answer:
We need to find the relations between the degree and radians. There are two ways to express the angles. They are degree and radians. The way to differentiate them is using the degree sign on the angle value.
If the angle is $x$, then it means it’s $x$ radian and if it’s given ${{x}^{\circ }}$, then that means $x$ degree.
The relation between these two units is that 180 degree is equal to $\pi $ radian. The value of $\pi $ is usual value where $\pi =3.14$. (approx.)
Therefore, $\pi \text{ rad}={{180}^{\circ }}$.
We can convert it into radian using the relation where 1 degree is equal to $\dfrac{\pi }{180}$ radian. This gives $x$ degree is equal to $\dfrac{\pi x}{180}$ radian.
We have to find the radian value of ${{570}^{\circ }}$.
We take $x=570$as multiplication of the relation for $\dfrac{\pi x}{180}$.
We get \[{{570}^{\circ }}=\dfrac{\pi \times 570}{180}\text{ rad}=9.95\text{ rad}\].
Therefore, ${{570}^{\circ }}$ is equal to \[9.95\text{ rad}\].

Note: Degrees and radians are ways of measuring angles. A radian is equal to the amount an angle would have to be open to capture an arc of the circle's circumference of equal length to the circle's radius.
