Explicação
The volume of a cylinder is given by the formula V = πr²h, where r is the radius of the base, h is the height, and π is a constant approximately equal to 3.14159. In this case, we are given that the diameter of the base is 12 cm, so the radius is 12/2 = 6 cm. The height is given as 5 cm. We are also told to use π = 3 for this calculation. Substituting these values into the formula gives V = 3 * 6² * 5 = 540 cm��. Therefore, the minimum volume of the garbage bag that Danilo needs to buy is 540 cm��.
