l=2 \pi r(  \frac{ \alpha }{360} ) <-- alpha is the degree 

l=2 \pi (12)(9/360)

Solve −3x2 − 4x − 4 = 0
kkurt [141]
This is a quadratic formula with a general form of a²x + bx + c = 0. For quadratic equations, we can solve for its two roots using the quadratic formula shown in the attached picture.

a = -3
b = -4
c = -4

x = [-(-4) + √(-4)² - 4(-3)(-4)]/2(-3) = <em>2 + √-32/2</em>
x = [-(-4) - √(-4)² - 4(-3)(-4)]/2(-3) =<em> 2 - √-32/2</em>
