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?

The answer to your question is 301.44 m²

Step-by-step 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

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
