Total surface area of hemisphere

1. A hemisphere is a 3D geometric shape that represents half of a sphere, obtained by cutting the sphere into two equal halves along the equator.

2. Hemisphere formula: Total surface area of a hemisphere = 3πr²

(1) π is the mathematical constant pi, approximately equal to

(2) r is the radius of the sphere

3. Since a hemisphere is half of a sphere, its total surface area is also half of the sphere’s total surface area, including the cross-sectional area of the hemisphere.
