The total volume of the three cylinders is given by: V = (3) * (pi) * (r ^ 2) * (d) Where, r: cylinder radius d: cylinder depth Substituting values we have: V = (3) * (3.14) * (4 ^ 2) * (7) V = 1055.04 feet ^ 3 Answer: the volume of oil needed is: V = 1055.04 feet ^ 3
The perimeter is the sides of the hexagon. One of the hexagon edges is shared with a rectangular face. Solve for that edge. 78/6=13. The height is the length and edge is the width. Area is length(16) times width(13). 16•13=208. The answer is 208mm^2
