Where
--- lower radius
--- upper radius
And
---- l represents the slant height of the frustrum
So, we have:
Solving (b): The volume
This is calculated as:
This gives:
-|20| + |5| = -15
Steps:
Apply absolute rule: |a| = a, a >/ 0
|20| = 20
= -20+5
Apply absolute rule: |a| = a, a >/ 0
|5| = 5
= -20+5
Refine
= -15
Hope this helps you! (:
