So this is like a pie chart or fractions
20 degreees is x% or x/whole parts
circle=360degrees
20/360=2/36=1/18
so the area represents 1/18 of the circle
684=1/18 of circle
multply both sdies by 18
12312=18/18 circle
the area of the circle=12312 yd^2
Plug in -3 for x.
f(-3) = 0.5(3 - (-3))
f(-3) = .5(6)
f(-3) = 3
