What is the area of the base of a cylinder with a volume of 174π in.3 and a height of 12 inches? 1. Apply the formula for the volume of a cylinder: V = Bh 2. Substitute the known measures into the formula: 174π = B(12) 3. Apply the division property of equality: 174π 12 = B 12 12 The area of the base of the cyclinder is π in.2.
