so you simply plug your value for radius into the equation!
$\pi {(14)}^{2}$
Square 14
$196\pi$
And Multiply by pi!
615.75 cm^2 approximately!
I hope this helps!

Please help!!! <br> I’m so bad at math.

Answer:

x = - 9 , 6

Step-by-step explanation:

The given function is

$h(x) = \frac{x - 8}{x^{2} + 3x - 54}$

⇒ $h(x) = \frac{x - 8}{(x - 6)(x + 9)}$

Therefore, the value of h(x) will be undefined for the denominator equal to zero.

So, (x + 9)(x - 6) = 0

⇒ x = - 9 and x = 6

Therefore, the values of x which are not in domain of function h(x) are x = - 9 , 6. (Answer)
