Answer:

384π cm³

Step-by-step explanation:

Formula for the volume of a cone is \displaystyle \large{\frac{1}{3}\pi r^2 h} where:—

  • r is radius
  • h is height

Our radius is given in an attachment which is 12 cm and height is 8 cm. Substitute these values in the formula:—

\displaystyle \large{V = \frac{1}{3}\pi (12)^2 \cdot 8}\\\displaystyle \large{V = \frac{1}{3}\pi \cdot 144 \cdot 8}\\\displaystyle \large{V = 48 \pi \cdot 8}\\\displaystyle \large{V = 384 \pi}

__________________________________________________________

<u>Summary</u>

  <u>Volume (Cone)</u>

\displaystyle \large{V = \frac{1}{3}\pi r^2 h} where:—

h is height or perpendicular.

r is radius.

  <u>Value of Pi (Commonly Used)</u>

\displaystyle \large{\pi \approx 3.14}

Find the difference (3-13x-7x^2)-(5x^2+ 12x-10)
Nikolay [14]
3 - 13x - 7x^2 - (5x^2 + 12x - 10)
Distributing the negative over the parentheses chamges the signs:-
= 3 - 13x - 7x^2 - 5x^2 - 12x + 10
adding like terms:-
= -12x^2 - 25x + 13  (answer).

WhaThe factorization of x2 + 3x – 4 is modeled with algebra tiles.t is the factored form of x2 – x – 2?
Nataly [62]

Answer:

  x^2 -x -2 = (x -2)(x +1)

Step-by-step explanation:

To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:

  -2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1

Then these are the constants in the binomial factors:

  x^2 -x -2 = (x +1)(x -2)

_____

<em>Comment on the question</em>

The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.

The sum of Eli’s age and Cecil’s age is 60. Six years ago, Eli was three times old as Cecil. Find Eli’s age now
Nesterboy [21]

Answer:

Eli's age = 42 years

Step-by-step explanation:

Let x be Eli's age and y be Cecil's age

So,

According to the statement given

x+y=60     eqn 1

Eli's age 6 years ago = x-6

Cecil's age 6 years ago = y-6

So according to the given statement

x-6 = 3(y-6)

x-6 = 3y - 18

x-3y = -18+6

x-3y= -12      eqn 2

Subtracting eqn 2 from eqn 1

x+y - (x-3y) = 60 - (-12)

x+y-x+3y = 60+12

4y = 72

y = 18

Cecil's age = 18 years

Putting y = 18 in eqn 1

x+18=60

x = 60-18

x = 42

Eli's age = 42 years ..
