a.
To determine the volume and lateral area of the cone
a.
Answer to Problem 28WE
The volume and lateral area of the cone is
Explanation of Solution
Given: Consider thegiven information,
The segment is rotated about the x-axis forming the lateral surface of the cone.
Radius of cone = 3 units
Height of cone = 4 units
Formula Used:
Volume =
Lateral area =
Calculation: Consider the given information the formula is,
Volume =
Lateral area =
Conclusion:
The volume and lateral area of the cone is
b.
To determine the volume and lateral area of the cone

Answer to Problem 28WE
The volume and lateral area of the cone is
Explanation of Solution
Given: Consider thegiven information,
The segment is rotated about the y-axis forming the lateral surface of the cone.
Radius of cone = 4units
Height of cone = 3units
Formula Used:
Volume =
Lateral area =
Calculation: Consider the given information the formula is,
Volume =

c.
Are the parts (a) and (b) the same
c.
Answer to Problem 28WE
No the parts (a) and (b) the same
Explanation of Solution
Given: Consider thegiven information,
The segment is rotated about the x-axis forming the lateral surface of the cone.
Radius of cone = 3units
Height of cone = 4units
The parts (a) and (b) are not same because the axis of rotation are different.
