The ecology class would like to create a circular vegetable garden to grow various organic fruits and vegetables. One sector of the garden will need a special type of soil for growing blueberries. The students would like to put a
rock barrier between the blueberries and other vegetables to designate the area. The area of the sector of
blueberries is 247 ft2, and the central angle is - 600. Find the length of the rock barrier (i. e., the radius of the
circle).
A. r = 2 ft
B. r = 8.48 ft
C. r= 12 ft
D. r= 144 ft

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
