Spherical Zone Calculator: Find the Surface Area of a Spherical Zone Instantly

Calculate Spherical Zone Surface Area

Enter the radius of the entire sphere.
Enter the height of the zone (distance between parallel planes).

Results:

Surface Area (A): square units

Unlock quick and accurate solutions for your geometry challenges with our Spherical Zone Calculator. Simply enter the sphere's radius and the zone's height to instantly compute the surface area. Ideal for students, engineers, and designers.

Formula:

The surface area of a spherical zone is calculated using the formula:
A = 2πRh
Where:

  • A = Surface Area of the Spherical Zone
  • π (Pi) ≈ 3.14159
  • R = Radius of the sphere
  • h = Height of the spherical zone (the perpendicular distance between the two parallel planes defining the zone)
