Answer:2355.31\ cm^3

Step-by-step explanation:

Given

diameter of the cone is  d=23\ cm\quad [r=\frac{d}{2}=11.5\ cm]

The height of the cone is  h=17\ cm

The volume of a cone is  V=\dfrac{1}{3}\pi r^2h

Insert the values

\Rightarrow V=\dfrac{1}{3}\times \dfrac{22}{7}\times 11.5^2\times 17=2355.309\\\\\Rightarrow V\approx 2355.31\ cm^3

Thus, the volume of the cone is 2355.31\ cm^3

UNO [17]
X² + 11x + 28 + x² + 13x + 40

combine like terms

x² + x² = 2x²
11x + 13x = 24x
28 + 40 = 68

2x² + 24x + 68 is your answer

if you want it simplified: 

2(x² + 12x + 34)

Find the discriminant of the following quadratic equation then state the number of rational, irrational, and imaginary solutions
lianna [129]

Answer:

  • -6x² - 6 = -7x - 9
  • -6x² + 7x - 6 + 9 = 0
  • -6x² + 7x + 3 = 0
  • 6x² - 7x - 3 = 0

<u>Discriminant:</u>

  • D = (-7)² - 4*6*(-3) = 49 + 72 = 121

<u>Since D > 0, there are 2 real solutions:</u>

  • x = (- (-7) ±√121 )/12
  • x = (7 ± 11)/12
  • x = 1.5, x = -1/3
