It's Getting Hot in Here!

It's been over 90 degrees every day this week so Miles decides that he wants to take a swim. What does this have to do with math? Well, lets see!

Step 1
Miles gets out his doggy pool and measures the diameter. He finds that it is 35 inches across.


Step 2
Miles fills the pool with water.



Step 3
Make sure the water doesn't overflow! Boy, it sure is hot out here!
Step 4
Miles measures the water depth and finds out it is 4 inches deep.

Step 5
Miles calculates the volume of water in the pool.

He knows that the pool is a cylinder because it’s base is a circle with a diameter of 35 inches and it has a height of 4 inches. The pool's radius will be half of the diameter, which makes it 17.5 inches. In grad school he learned that the formula for calculating the volume of a cylinder is V=3.14*r^2*h.

So he fills in what he knows and solves for the unknown, which is volume.

V=(3.14)(17.5in)^2(4in) so the volume of the water in the pool is 3,846.5 in^3.


Good boy, Miles!

Step 6
Nothing left to do but invite some lovely ladies and go for a swim!




Miles is such a show-off!
