diameter = 18 inches
radius = r = 18/2 = 9 in
Volume of cylinder = 405π/2
h = 2.5 inches
I think the variation is x. because for have the y-intercept if yo move x
Let θ = m∡I
tan θ = 20/21
tan⁻¹ (20/21) = θ
θ ≈ 43.60° or if you need to round to another decimal point, plug the equation I put in bold into a calculator.
Check the picture below.
make sure your calculator is in Degree mode.
