The parabolic segment

The parabolic segment has a base a = 4 cm and a height v = 6 cm. Calculate the volume of the body that results from the rotation of this segment

a) around its base
b) around its axis.

Correct result:

V1 =  0 cm3
V2 =  50.2655 cm3

Solution:

a=4 cm v=6 cm f(x)=qx2 f(a/2)=q(a/2)2=v 6=q 22  V1=q=6/22=32=1.5=0 cm3
