Spherical segment

Calculate the volume of a spherical segment 18 cm high. The diameter of the lower base is 80 cm, the upper base 60 cm.

Correct result:

V =  73739.4628 cm3

Solution:

h=18 cm D1=80 cm D2=60 cm  r1=D1/2=80/2=40 cm r2=D2/2=60/2=30 cm  V=π⋅ h6⋅ (3⋅ r12+3⋅ r22+h2)=3.1416⋅ 186⋅ (3⋅ 402+3⋅ 302+182)=73739.4628 cm3
