A cosmetics industry wants to manufacture a cylindrical perfume bottle for its new launch. The bottle should have a height of 10 cm and a volume of 500 cm³. Additionally, the factory has decided that the total surface area of the bottle, including the base and the top, should be minimized to reduce the amount of material used. Considering that the base area of the cylinder is directly proportional to the cylinder's volume and that the total surface area (A) of a cylinder with radius (r) and height (h) is given by A = 2 * pi * r * (r + h), calculate the radius (in cm) that minimizes the total surface area of the bottle. After finding the value of the radius that meets this requirement, check if the dimensions (height and radius) of the proposed bottle simultaneously meet the volume and total surface area conditions established by the industry. If the dimensions do not meet both requirements, discuss why this occurs and suggest adjustments that could be made to optimize the bottle shape, while keeping the height constant at 10 cm.Answer sheet:

The image presented in the figure is a black and white copy of the square canvas titled The Fish, by Marcos Pinto, which was placed on a wall for exhibition and fixed at points A and B (figure 1). Due to a problem in fixing one of the points, the canvas detached and rotated close to the wall. After the rotation, it was positioned as illustrated in figure 2, forming a 45° angle with the horizon line. Figure 1 Figure 2 To put the canvas back in its original position, it should be rotated, close to the wall, at the smallest possible angle less than 360°. The way to put the canvas back in the original position, following what was established, is by rotating it at an angle of

The Science class is learning about vegetable gardens and decided to plant a small rectangular garden at school, where they will grow lettuce and carrots. The garden's rectangle measures 3 meters in length and 2 meters in width. To find out how many plants will fit in the garden, they need to calculate the perimeter. Help the students calculate the perimeter of this rectangular garden.

In a renovation, an architect decides to completely cover a right prism with a square base with ceramic tiles that are in the shape of squares. The prism is 3 meters high and the edge of the base measures 2 meters. The tiles are 20 cm on each side. The architect will need to calculate the amount of tiles to cover the entire surface of the prism. How many tiles will be needed to completely cover the prism?
