A cylinder is a three-dimensional shape with two circular bases connected by a curved surface
The axis of a cylinder is a straight line connecting the centers of the two bases
Cylinders can be classified as right, oblique, or elliptic based on the orientation of their axis and shape of their bases
The lateral surface area of a cylinder is the area of the rectangle formed by unrolling the curved surface
The total surface area of a cylinder is the sum of the lateral surface area and the areas of the two bases
Half cylinders have a curved surface and one circular base, and their surface area can be calculated using a modified formula
Capped half cylinders have a flat rectangular cap and their surface area formula includes the area of this cap
The lateral surface area of a cylinder is calculated by multiplying the height and circumference of the base
The total surface area of a cylinder is calculated by adding the lateral surface area to the areas of the two bases
The surface area of a half cylinder is calculated by adding the lateral surface area to the area of one base
The surface area of a capped half cylinder is calculated by adding the lateral surface area, the area of one base, and the area of the rectangular cap
