Find the volume of the earth. V=4/3 pi r cubed
Problem 2: what is the sin0 in this triangle? use diagram above the real life example. C=13 and b=12 when angle A is your sin 0.
A: 5/13=sin0 in this problem. sin0=cos90
prove Pythagorean theorem
A: use either "square" or "four triangles"
Is this possibly a fractal?
