The image above is a spherical segment. To calculate the volume of a spherical segment requires three essential parameters which are the radius of the spherical segment base (r1), the radius of the spherical segment (r2), and height (h).
The formula for calculating the volume of the spherical segment:
V = πh(3r1² + 3r2² + h²) ⁄ 6
Where;
V = Volume of the spherical cap
r1 = Radius of the spherical segment base
r2 = Radius of the spherical segment base
h = Height of the spherical segment
Let’s solve an example;
Find the volume of a spherical segment when the radius of the spherical segment base (r1) is 7 cm, the radius of the spherical segment base (r2) is 9 cm, and a height of 20 cm.
This implies that;
r1 = Radius of the spherical segment base = 7 cm
r2 = Radius of the spherical segment base = 9 cm
h = Height of the spherical segment = 20 cm
V = πh(3r1² + 3r2² + h²) ⁄ 6
V = π x 20(3 x 7² + 3 x 9² + 20²) ⁄ 6
That is, V = π x 20(3 x 49 + 3 x 81 + 400) ⁄ 6
V = π x 20(147 + 243 + 400) ⁄ 6
V = π x 20(790) ⁄ 6
So, V = π x 15800 ⁄ 6
V = 49643.6 ⁄ 6
V = 8273.9
Therefore, the volume of the spherical segment is 8273.9 cm3.
