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 answer:

V =  73739.4628 cm3

Step-by-step explanation:

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=7.374104 cm3
