If each box has the cost of 23 cents, and you decided to buy 4, you would multiply the amount of boxes you want with the cost of each one, therefore, the 92 cents. 4 * 23 = 92
We have the following equation: V = (1/3) * (pi) * (r ^ 2) * (h) To clear r we must follow the following steps: 1) Divide both sides of the equation by pi*h 2) Multiply both sides of the equation by 3 3) take de square root of both sides of the equation
