Volume

Not audio, but what's left inside a box.

A sphere. To find its volume, use
4/3 * 3.14 * r^3.

A cylinder. It's volume can be found with 3.14 * r^2 * h.

To discover this cone's volume, use the same formula for our cylinder, but divide your result by 3.

Pythagorean theorem

Let's try using

It's truly simple, use:
a^2 + b^2 = c^2, making a and b your triangle's legs.
So, when you find what the sum of a and b squared is, square root it!

But what if you know c, not b?
Simple: c^2 - a^2 = b^2.

Area

So you need to find the

This is a parallelogram. Use
A = bh (or lw*h).

A circle? Easy:
A = 3.14 * r^2.

Finally, a single triangle.
A = 1/2 * b * h OR...
A = (b*h) /2
