Concept explainers
a.
To find: The find the volume of given solid.
a.
Answer to Problem 40E
The volume is 3.79646 Unit2.
Explanation of Solution
Given information :
The solid lies between planes perpendicular to the X-axis at
The cross-section perpendicular to the X-axis and circular disks with diameters running from the curve
Formula used : The volume of a solid of known integrable cross-section area
The area of a circle of diameter “
Calculation :
The cross-section perpendicular to X-axis is circular disk.
So, area is,
Volume of the solid is,
So, the required volume is 3.79646 Unit2.
b.
To find: The find the volume of given solid.
b.
Answer to Problem 40E
The volume of the solid is approximately
Explanation of Solution
Given information : The solid lies between planes perpendicular to the X-axis at
The cross-section perpendicular to the X-axis and circular disks with diameters running from the curve
Formula used : The volume of a solid of known integrable cross-section area
The area of the Square of side “
The cross section perpendicular to X-axis is a square.
So, the area
Volume of the solid is,
The volume of the solid is approximately
