Question

Find the surface area of a conical grain storage tank that has a height of 42 meters and a diameter of 20 meters. Round the answer to the nearest square meter.

Answer 1

surface area of a cylinder is 2(pi)(r)^2 + 2(pi)(r)(h)

radius is half of the diameter so 10 meters

2(pi)(10)^2 + 2(pi)(10)(42)
2(pi)(100) + 2(pi)(420)
200(pi) + 840(pi)
1040(pi)
3267.26

Final Answer: 3267 square meters
