Please see the attached file.
Determine the volume and total surface area of the body.
Please show all steps in detail.
NOTE: we can take this object a hallow half frustum cone .
a1= 94 a2= 42
b1= 20 b2=20
h1= 60 h2=60
1) Volume = (1/3) Phi (h)( a^2 + ab + b^2)
Volume of object = Volumeof OuterObject - Volumeof InnerObject
note: object is in shape of truncated cone
applying volume of
Volumeof OuterObject ...
The solution explains how to calculate the volume of the given solid after rotation.
