PLZ HELP ASAP CROSS SECTIONS OF 3D FIGURES LAST ONE

The answer would be a rectangle. Same as the previous question, when you split up a cylinder, then  it will give you two rectangles due to its vertical sides. The other choices is impossible because when you say it will result into a square, the arc of the circle must be the same as the height of the cylinder to result into a square. but it has different measurements so it is a rectangle, one side is bigger than the other.

Correct Answer is

Rectangle.

An isosceles triangle can be obtained from cross section of a cone.

Since the height of the cylinder is much larger than the diameter, the resulting cross sectional area would be a rectangle.

For a square, all four sides must be equal. So a cylinder with equal diameter and height will result in a square.

Find the radius of convergence R, then determine the interval of convergence
Hunter-Best [27]

The radius of convergence R is ∞ and the interval of convergence is (-∞, ∞) for the given power series. This can be obtained by using ratio test.  

<h3>Find the radius of convergence R and the interval of convergence:</h3>

Ratio test is the test that is used to find the convergence of the given power series.  

First aₙ is noted and then aₙ₊₁ is noted.

For  ∑ aₙ,  aₙ and aₙ₊₁ is noted.

\lim_{n \to \infty}  | \frac{a_{n+1} }{a_{n} } | = β

  • If β < 1, then the series converges
  • If β > 1, then the series diverges
  • If β = 1, then the series inconclusive

Here aₙ = (n²/n!) xⁿ⁺³  and  aₙ₊₁ = ((n+1)²/(n+1)!) xⁿ⁺¹⁺³ = ((n+1)²/(n+1)!) xⁿ⁺⁴

Now limit is taken,

\lim_{n \to \infty}  | \frac{a_{n+1} }{a_{n} } | = \lim_{n \to \infty}  | \frac{((n+1)^{2} /(n+1)!) x^{n+4}  }{(n^{2} /n!) x^{n+3}  } |

                      = \lim_{n \to \infty}  | \frac{((n+1)^{2} ) n!x^{n+4}  }{(n+1)!(n^{2} ) x^{n+3}  } |

                      = \lim_{n \to \infty}  | \frac{((1+1/n)^{2} ) x  }{(n+1)} |  

                      =   \lim_{n \to \infty}  | \frac{ x  }{(n+1)} |  = 0 < 1

Since the limit is less than 1 the series is converging.

We get that,

interval of convergence = (-∞, ∞)

radius of convergence R = ∞

Hence the radius of convergence R is ∞ and the interval of convergence is (-∞, ∞) for the given power series.
