Area of hemispherical surface

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

2. Hemisphere surface area formula: Hemisphere surface area = 2πr²

(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, the surface area of a hemisphere is also half of the total surface area of the sphere.
