Question

what is the surface area of a conical grain storage tank that has a height of 37 meters and a diameter or 16 meters round the answer to the nearest square meter

Answer 1

According to the formula, the lateral area of a conical is Sc=$\pi r \sqrt{r^{2} + h^{2} }$. The basal area S=πr². And the surface area equals Sc + S. So the answer is 1151.877≈1152 m².
