The radius r and height h of a right circular cone are both increasing at a constant rate of 2 cm/h. At what rate in centimeters

cubed per hour is the volume V of the cone increasing when r = 6cm and h = 15cm? (The volume V of a right circular cone of height h and radius r is V = 1πr2h.)

Answer:

94.2

Step-by-step explanation:

i honestly dont know if this answer is right but i am currently takeing classes in math about Geometry. We was learning about Word problems, that had to do with volume, Area, and perimeter, and learned what radius is, etc..

  • So i thought you take the formula it gives you and use. Since Pie means 3.14 you use that in the formula. V= 1×3.14×2×15 = 94.2
  • you would multiply everything together because every number is close together.
  • the height is 15 cm, thats how you get 15 at the end.
  • next step is to solve the equation in your calculator. and it gives you that number. = 94.2

Form the quadratic equation whose one root is 2 + 2^(1/2)​
Oksanka [162]

9514 1404 393

Answer:

  x^2 -4x +2 = 0

Step-by-step explanation:

The other root is the conjugate of the given one, so is 2-√2. The quadratic equation in factored form is then ...

  (x -2-√2)(x -2+√2) = 0

Expanding this, we get ...

  (x -2)^2 -(√2)^2 = 0

  x^2 -4x +4 -2 = 0

  x^2 -4x +2 = 0 . . . . the equation you're looking for
