Question

A cylindrical grain silo is being built for Mr. Greenjeans. The silo is 13 meters tall with a diameter of 6 meters. If the entire silo is being fabricated from sheet metal, how many square feet of sheet metal will be needed to complete the silo?

Answer 1

The answer to your question is 301.44 m²

Explanation:

Data

height = 13 m

diameter = 6 meters

Formula

Area of a cylinder = 2πr² + 2πrh

- Substitution

Area of a cylinder = 2(3.14)(3)² + 2(3.14)(3)(13)

- Simplification

Area of a cylinder = 56.52 + 244.92

-Result

Area of a cylinder = 301.44 m²
