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 24. ft?, and the central
angle is 9-60°. 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
