It does not include the area of the base which is in the shape of a circle. The lateral surface area is the area of the curved part of the hemisphere only. If the radius of a hemisphere is given, we can calculate the curved surface area (CSA) of a hemisphere by using this formula, Curved surface Area of a Hemisphere = 2πr 2, where π is taken as 3.142 or 22/7, and r is the radius of the hemisphere. What is the Formula to Find the CSA Area of a Hemisphere? It should be noted that this is the total surface area of the hemisphere which includes the area of the base too. The surface area of a hemisphere is the curved part of the hemisphere and we calculate it by using this formula, Surface Area of Hemisphere = 3πr 2, where π which is taken as 3.142 or 22/7, and r is the radius of the hemisphere. What is the Formula to Find the Surface Area of a Hemisphere? The volume of a hemisphere is expressed in cubic units and the formula which is used for the volume of a hemisphere is, Volume of Hemisphere = (2πr 3)/3, where π is the constant measuring 3.142 or 22/7, and r is the radius. What is the Formula to Find the Volume of a Hemisphere? Some of the real-life examples of a hemisphere are a bowl, igloo, the top part of a mushroom, and so on. It has one curved side and one flat side called the face of the hemisphere or the great circle of the sphere which helps in forming the hemisphere. FAQs on Hemisphere What is a Hemisphere Shape in Math?Ī hemisphere is a 3D figure which is obtained by cutting a sphere into two equal halves through its diameter.
