Answer:

About 28.26 inches.

Step-by-step explanation:

The formula for circumfrence is c = 2(pi) * r.

We know that r = 4.5 (because the diameter is 9 inches).

So, the equation is c = 2(pi) * 4.5

Let's solve:

c = (2*3.14) * 4.5

c = 6.28 * 4.5

c = 28.26

Therefore, the final answer is 28.26 inches.

Of course, this is not exact because pi is irrational and goes on forever, but the question is asking for an estimate anyways.

The volume of a cylindrical container

Ray Of Light [21]

Answer:

A. $\frac{3}{4}\textrm{ gal}$

Step-by-step explanation:

Given:

Volume of the cylindrical container before dilation, $V_{i}=1\textrm{ gal}$

Scale factor of the dilation, $SF=\frac{3}{4}$

Therefore, the volume of the dilated cylinder is given as:

$V_{f}=SF\times V_{i}$

Plug in 1 gal for $V_{i}$ and $\frac{3}{4}$ for SF. Solve for $V_{f}$ . This gives,

$V_{f}=\frac{3}{4}\times 1\\V_{f}=\frac{3}{4}\textrm{ gal}$

Therefore, the volume of the dilated cylinder is $\frac{3}{4}$ gallons.
