Final answer:
The volume of the cylinder is π(4 ft)^2h and the surface area is 2π(4 ft)h + 2π(4 ft)^2. The density and temperature of the liquid cannot be determined without additional information.
Step-by-step explanation:
The volume of a cylindrical container is given by the formula V = πr2h, where r is the radius of the base and h is the height. In this case, the base of the cylinder has a radius of 4 ft. Therefore, the volume of the cylinder is V = π(4 ft)2h.
The surface area of a cylinder is given by the formula A = 2πrh + 2πr2, where r is the radius of the base and h is the height. In this case, the base of the cylinder has a radius of 4 ft. Therefore, the surface area of the cylinder is A = 2π(4 ft)h + 2π(4 ft)2.
The density of a substance is defined as its mass per unit volume. In this case, the density of the liquid in the cylinder would depend on the specific liquid being used. Without that information, we cannot determine the density of the liquid.
The temperature of the liquid in the cylinder would also depend on the specific liquid being used. Without that information, we cannot determine the temperature of the liquid.
