Example 2:
Another task card shows a cylindrical container with a radius of 6 cm and a height of 10 cm. Students are asked to find the total surface area of the container, including the top and bottom parts. To solve this, students need to find the area of the base (using the formula for the area of a circle), the area of the curved surface (using the formula for the circumference of a circle and the height), and then add them together. The answer, in this case, would be 432 square centimeters.
Example 3:
A task card presents a cone with a radius of 3 cm and a slant height of 7 cm. The question asks students to determine the total surface area of the cone. To solve this, students need to find the area of the base (using the formula for the area of a circle), the area of the curved surface (using the formula for the circumference of a circle and the slant height), and then add them together. The answer, in this case, would be 111 square centimeters.
