Answer:

1130.4 cubic meters

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)πr^{2}·h = (1/3)*3.14*6^{2}*18 = 678.24 cubic meters

=> the volume of the small cone is:

V = (1/3)πr^{2}·h = (1/3)*3.14*6^{2}*12 = 452.16 cubic meters

=> the volume of the composite solid :

= 678.24 + 452.16

=1130.4 cubic meters

Answer:

Step-by-step explanation:

It's essential that you use the symbol " ^ " to indicate exponentiation.

Expanding f(x) = (x + 14)^2 results in x^2 + 28x + 196 (which is in standard form)
