A hemisphere is a three-dimensional shape with the following properties. Formed by dividing a sphere into two halves along its diameter. Each hemisphere consists of a curved surface and a flat circular base. This shape is commonly seen in everyday life, such as when cutting a cherry in half or dividing the Earth into the Northern and Southern Hemispheres. Hemispheres can be either solid, like a half-filled bowl, or hollow, like the top half of a spherical container. Properties of Hemisphere ... The area of a hemisphere is the total space covered by its surface. There are two types of areas for a hemisphere: Curved Surface Area (CSA): This is the area of only the round curved part of the hemisphere, without including the flat base. The formula for this is: CSA = 2πr² TSA = 3.14 × 48 TSA = 150.72 cm 2 Therefore, the curved and the total surface area of the hemisphere are 100.48 and 150.72 cm 2, respectively.

Surface Area of a Hemisphere The surface area of a hemisphere is defined as the region covered by the faces of the hemisphere. The total surface area of a hemisphere includes the curved surface area and the base area of the hemisphere. Let us learn more about the total surface area of a hemisphere and the curved surface area of a hemisphere along with solved examples.
