Question

lateral surface area of hemi sphere ?​

Answer 1

The lateral surface area of a sphere is given by 4\pi r^{2} where r is the radius of the sphere. Hence, the Curved Surface Area (CSA) of a Hemisphere is given by 2\pi r^{2} where r is the radius of the sphere of which the hemisphere is a part. The total surface area (TSA) of a Hemisphere is given by 3πr2.
