1. Answer:

   118.625

   Step-by-step explanation:

   volume of air inside= volume of two cones+volume of cylinder

   Volume of cones:

   radius=2

   height=2

   formula: 1/3*pie*r^2*h

   volume of two cones=2(1/3*pie*2^2*2)

   Volume of cylinder:

   radius=2

   height=8 (height of cyl=12- height of 2cones)

   formula: base area*height OR pie*radius^2*height

   volume of cylinder=pie*2^2*8

   Total Volume=2(1/3*pie*2^2*2)+pie*2^2*8
