PLEASE HELP, I WILL MARK BRAINLIEST FOR THE FIRST CORRECT ANSWER))

Answer:

The volume of this cylinder is 9184.5 cubic feet.

Step-by-step explanation:

The area of a circle is $\pi r^2$ and the volume of a cylinder with that base is just that area times the height:

$V=\pi r^2\times h$

Here, we're given the diameter, but we need the radius. The radius of a circle is just half of the diameter:

$r=30\times0.5=15$

Next, you can use that radius to calculate the area of the base:

$A=3.14\times15^2\\A=3.14\times225\\A=706.5$

Finally, multiply that by the height to find the volume of the cylinder:

$V=706.5\times13\\V=9184.5$

The volume of this cylinder is 9184.5 cubic feet.

What is 321.5 Kilometers per hour converted to MPH

inessss [21]

$321.5\ kmph\approx\boxed{199.770777\ mph}$

By the way, Google has a built in calculator. You can just type in "321.5 kmph in mph" and it will come up with this answer.

You could also use the fact that $1\ km\approx0.621371\ mi$ ,
According to the properties of equality, if you have two equal expressions and you change them in the same way, the results wil also be equal.
So that means we can multiply each side by 321.5 and get our answer above.
