## Answers

**Answer:**

The surface area of a cylinder is the area occupied by its surface in a three-dimensional space. A cylinder is a three-dimensional structure having circular bases which are parallel to each other. It does not have any vertices. Generally, the area of the three-dimensional shapes refers to the surface area. The surface area is represented in square units. For example, cm2, m2, and so on. A cylinder can be seen as a set of circular disks that are stacked on one another. Since the cylinder is a solid of a three-dimensional shape, it has both surface area and volume.

The cylinder area is defined as the sum of the curved surface and the area of two circular bases of the cylinder.

The Surface Area of Cylinder = Curved Surface + Area of Circular bases

S.A. (in terms of π) = 2πr (h + r) sq.unit

Where, π (Pi) = 3.142 or = 22/7

r is the radius of the cylinder

h height of the cylinder

As we know, a cylinder has two types of surfaces, one is the curved surface and the other is the circular base. So the total surface area will be the sum of the curved surface and two circular bases.

**Step-by-step explanation:**

formula

The Surface Area of Cylinder = Curved Surface + Area of Circular bases

S.A. (in terms of π) = 2πr (h + r) sq.unit

Where, π (Pi) = 3.142 or = 22/7

r is the radius of the cylinder

h height of the cylinder
