Question 1162352: Determine the total surface area in square meters of a grain silo with cylindrical shape with a conical roof. Diameter of the cylinder is 20 meters, the height of the cylinder is 15 meters from the ground, and height of cone is 4 meters from the top of cylinder. Total surface area shall include the base of cylinder (floor).

Base of cylinder: %28pi%29%28r%5E2%29

Lateral surface area of cylinder: %282pi%28r%29%29%28h%29

Lateral surface area of cone: %28pi%29%28r%29%28l%29
where l is the slant height. Determine the slant height using the radius of the base of the cone (i.e., radius of the cylinder) and the height of the cone.

You can do the calculations.
