A cylinder is a three-dimensional figure that consists of two circular bases and a curved surface connecting the bases. Let's break down the components of a cylinder to understand why the correct answer is option 'B' - 3 surfaces.
1. Circular Bases:
A cylinder has two circular bases that are congruent and parallel to each other. These bases are perfectly flat and have the shape of a circle. The bases are connected by a curved surface, which forms the lateral surface area of the cylinder.
2. Curved Surface:
The curved surface of a cylinder wraps around the lateral area, connecting the two circular bases. It is in the shape of a rectangle that has been curved around to form a tube-like structure. The curved surface does not include the circular bases but encompasses the rest of the cylinder's surface area.
3. Lateral Surface Area:
The lateral surface area refers to the curved surface of the cylinder. It is formed by unrolling the curved surface of the cylinder into a flat rectangle. The lateral surface area is calculated by multiplying the height of the cylinder by the circumference of one of its circular bases.
4. Total Surface Area:
When we consider all the surfaces of a cylinder, including the two circular bases and the curved surface, we get the total surface area of the cylinder. The total surface area is calculated by adding the areas of the two circular bases and the lateral surface area.
In conclusion, a cylinder has two circular bases and a curved surface, making a total of three surfaces. The circular bases are flat and circular, while the curved surface wraps around the lateral area. Therefore, the correct answer is option 'B' - 3 surfaces.
