So I was studying some circle properties in Khan Academy and this problem basically states that if:
$S=r\theta$
then find a formula for $S$ in terms of $r$. Now in the problem it says that the angle equals 5.6 radians but then the answer says that:
$S=r(1.2)$
The problem says this... right below the circle (the angle of the image it's a central angle in radians)
Step 1: A central angle $\theta$ measured in radians tells us how many times the radius fits in the arc
$\text{arc longitude} = \text{radius} * \theta$
Step 2: Substitute
$S= r * 1.2$ <---- ????
Step 3: Formula it's:
$S= r * 1.2$
Why is it 1.2????
