Acylindrical container has a diameter of 14 inches and a height of 6 inches. since one gallon equals 231 cubic inches, the capacity of the tank is approximately

63 cups

V = πr2h → V = 3.14(42)(18) → V = 3.14(16)(18) = 904.32 in3 →  

904.32 in3

14.4 in3 per cup

≈ 62.8 cups → ≈ 63 cups

Step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

final total: 63
