Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
My answer:
The composite solid has two cones:
- The height of the big cone is: 12 m
- The height of the small cone is: 18
- The radius of the common base of the two cones is: 6 m
=> the volume of the big cone is:
V = (1/3)π·h = (1/3)*3.14*
*18 = 678.24 cubic meters
=> the volume of the small cone is:
V = (1/3)π·h = (1/3)*3.14*
*12 = 452.16 cubic meters
=> the volume of the composite solid :
= 678.24 + 452.16
=1130.4 cubic meters
