Answer:  1)  V = 37.68 [tex]ft^{3}[/tex]

               2)  V= 301.44 [tex]cm ^{3}[/tex] (Equal volumes)

Step-by-step explanation:

1) Total volume of all 3 cones =  3v, where (V) is volume for 1 cone.

Right circular cone: line segment from point to center base = height

                line segment from center base to circumference (circle) = radius

     V = [tex]\frac{1}{3}[/tex] b * h         b = [tex]\pi r^{2}[/tex]     (r ) = 2ft     ([tex]\pi[/tex])= 3.14    (h ) = 3ft

  V = [tex]\frac{1}{3}[/tex] ( [tex]\pi r ^{2}[/tex] ) * 3

 V = [tex]\frac{1}{3}[/tex] (3.14)( [tex]2^{2}[/tex] ) * 3  

  V = [tex]\frac{1}{3}[/tex] (3.14) (4) * 3

 V =  (1 )(3.14)(12)  ÷ 3

  V = 37.68  ÷ 3

 V =  12.56 [tex]ft ^{3}[/tex]   then for total of all 3:  12.56 * 3 = 37.68 [tex]ft ^{3}[/tex]  ( V = cubed unit)

2)  Cone: V = [tex]\frac{1}{3}[/tex] b * h  =  { [tex]\frac{1}{3}[/tex] ([tex]\pi[/tex]) ([tex]6^{2}[/tex] ) (8) } = { (3.14) (36) (8) ÷ 3 } = { 904.32 ÷ 3 } =        

              V = 301.44 [tex]cm ^{3}[/tex]

    Cylinder: V= [tex]\pi r ^{2}[/tex] h = {(3.14) ([tex]4 ^{2}[/tex] ) (6)} = { 3.14 * 16 * 6)=

                      V = 301.44 [tex]cm ^{3}[/tex]
