Equation 1: x² + y = 7

Equation 2: 3x + 7 = 9

Use Equation 2 to solve for "x" and plug in "x" into Equation 1 to solve for "y".

3x + 7 = 9

3x = 2

x = \frac{2}{3}

*********************************

x² + y = 7

(\frac{2}{3})² + y = 7

\frac{4}{9} + y = 7

y = 7 - \frac{4}{9}

y = \frac{63}{9} - \frac{4}{9}

y = \frac{59}{9}

Answer: (\frac{2}{3}, \frac{59}{9})

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}
