#### What is the formula for a hemisphere?

x 2 + y 2 + z 2 = R 2. The Cartesian form or equation of a hemisphere with the radius “R” at the point (x 0, y 0, z 0) is written as. (x-x 0) 2 + (y- y 0) 2 + (z- z 0) 2 = R 2. Therefore, the spherical coordinates of the hemisphere are given as follows. x = r cos θ sin ∅. y = r sin θ cos ∅. z = r cos ∅.
