Y - 8 =(-8/9)(x - 3)
y - 24/3 = (-8/9)x + 8/3
y = (-8/9)x + 32/3
<span>arc length = circumference • [central angle (degrees) ÷ 360]
Solving this equation for circumference:
</span>
<span>circumference = arc length / (central angle / 360)
</span><span>circumference = 12 / (85/360)
</span>circumference = 12 / <span><span>0.2361111111
