A cylindrical metal drum manufacturer produces drums with open tops. Each drum can hold 4 cubic meters. What is the cost of producing each drum if the metal used cost 10 dollars per square meter? Other materials and labor cost 3 dollars per drum. Neglect waste in cuttings.
Cylinders
A cylinder is a three-dimensional solid shape with two parallel and congruent circular bases, joined by a curved surface at a fixed distance. A cylinder has an infinite curvilinear surface.
Cones
A cone is a three-dimensional solid shape having a flat base and a pointed edge at the top. The flat base of the cone tapers smoothly to form the pointed edge known as the apex. The flat base of the cone can either be circular or elliptical. A cone is drawn by joining the apex to all points on the base, using segments, lines, or half-lines, provided that the apex and the base both are in different planes.
All answers must be accurate to 4 decimal places. Not in fraction and must be enclosed in a box or rectangle.
