I have to determine how long a pvc pipe is. The altitude is 8, the base is 12.

How would I go about finding the answer to this problem?

I came up with 8^2*12/2^2

sqrt is 100 which equals to 10

is that right?

I'm not sure what you mean by the "altitude" and "base."

If the altitude is the same as the length, then the length is 8.

Is the "base" value the diameter, the radius, the circumference or the area?

The first thing you need to do in finding an answer is become more specific in evaluating your data.

However, it may just be that you are using terms that are not familiar to me.

I hope this helps. Thanks for asking.
