Answer:

254.47 in²(rounded to nearest hundredth)

_________________________________________________________

$A = \pi r^2$

tiny r means radius

² means multiply the number by itself twice

$\pi r^2 = \pi * 9^2 = 81\pi(254.47~in^2)$

Gre4nikov [31]

Hi!

I believe this will answer your question the parent function of f(x) = 5x − 1 is 5, the parent function of g(x) = 3^x − 9 is 3^x ln (3), and g(x) − f(x) is -5f+g*3^x ln (3)

Jun used x milliliters, or 90% percent, of his favorite bottle of hot sauce.

Verizon [17]

Answer:

The volume of the full bottle of Jun's favorite hot sauce in ml is $\frac{10x}{9}$ .

Step-by-step explanation:

Jun used x milliliters, or 90% percent, of his favorite bottle of hot sauce.

So, to find the volume of a full bottle of Jun's favorite hot sauce in milliliters, we can use the unitary method.

Then, 90% of the full bottle sauce is equal to x ml.

So, 1% of the full bottle sauce is equal to $\frac{x}{90}$ ml.

Therefore, 100% of the full bottle sauce is equal to $\frac{x}{90}\times 100 = \frac{10x}{9}$ ml.

Therefore, the volume of the full bottle of Jun's favorite hot sauce in ml is $\frac{10x}{9}$ . (Answer)
