That is very good. I thought you said math was you best subject?

]]>Meanwhile I figured out the first 10 from the next lesson but need help with the second 10. The lesson is "The Cartesian Coordinate System and the Distance Formula" I'll wait for you to wake up and reply. Thanks again for the previous lesson!

E SQRT(173)

F SQRT(180)

Never mind! I got them all and sent them in and got 20/20!

]]>(You don't need to find actual numbers, just outline the method in step by step detail--think of all the measurements you'll need to acquire and how you'll get them.)

The problem asks for a general procedure not an analytical answer. I have provided both by coming up with the analytical answer.

I am going offline now to sleep.

]]>Can you write formula and solve it in step WRITTEN DOWN

So I could copy it.]]>

155.13135516116026 inches^2

The next formula is the volume I get,

162.6162806698982 inches^3

]]>I have no idea what's going on.

So what is b?
