Sondra has a conical bird feeder with a circular top. The volume of the bird feeder is 153.86 cubic inches. The height of the feeder is 12 inches. What is radius of the top? Use 3.14 for mc019-1.jpg. Round the answer to the nearest tenth.
Ms. Sue
V = π * r² * (h/3)
153.86 = 3.14 * r^2 * 4
153.86 = 12.56 * r^2
153.86/12.56 = r^2
12.25 = r^2
3.5 = r
