What is the area of a circular cardboard piece needed for the base of a model of a volcano that is 20 centimeters tall and has a volume of 960 cubic centimeters?
Which equation represents this real-world problem?
V = one-third (960) (20)
20 = one-third 960 (h)
960 = one-third pi 10 squared h
960 = one-third B (20)
