A circular piece of dough once baked has a thickness of "a" centimetres.

And a radius of "z" centimetres.

What is the total volume of the bread?

Must be a trick question.

Obviously thickness x pi x radius is the simple answer.

But what about the volume of the hollow spaces inside the bread caused by the yeast?

The radius is z ... not r.

And the thickness is equal to a.

You have two days to figure it out.

Is it a doughnut?

If so, and "z" is the average radius... I would say:

V = pi*a²/4*2*pi*z

V = 1/2*pi²*a²*z

STALKER ALERT!!

Thank you for inviting donuts into this conversation

Way off!

It is just a simple cylinder. ... NO DONUT

Clue:

Thickness "a" could be thin or thick.

I like mine with extra peperami and no anchovies.

Ok...

Its not: pi*z²*a?

Edit: Oh is see (I think) it's pizza!
