2. How much water could my well hold if the depth of the well is 30ft and the diameter of the well is 24ft?

Ann [662]

Answer:

$V=4,320\pi\ ft^{3}$ or $V=13,564.8\ ft^{3}$

Step-by-step explanation:

we know that

The volume of the cylinder (the well) is equal to

$V=\pi r^{2} h$

where

$r=24/2=12\ ft$ ----> the radius is half the diameter

$h=30\ ft$

substitute

$V=\pi (12)^{2}(30)$

$V=4,320\pi\ ft^{3}$

assume

$\pi =3.14$

$V=4,320(3.14)=13,564.8\ ft^{3}$

9x4=36
51-36=15
15÷3=5

therefore (I think) there should be 5 inches between each picture.

Find the perimeter of the triangle with vertices (−2,2), (0,4), and (1,−2). the perimeter is . round to the nearest hundredth.

mina [271]

The answer is about 12.5 (when rounded to the nearest 10th).

This can be found using the distance formula between each point. One distance is 5, one is $\sqrt{2}$ and one is $\sqrt{37}$ . Added together gives you the answer above.
