you cant solve that YOU FREAK!
pi is not divided into anything - unless you specify pi/2 or pi/3.6
sin (pi/2) = 1
PI x A x B PI=3,14 A=the longest side of the elipse divided by 2 B=the shortest side of the elipse divided by 2 PI x A x B PI=3,14 A=the longest side of the elipse divided by 2 B=the shortest side of the elipse divided by 2
0
It is 2*pi/3.

2/pi is about 0.6366197724

It is 2*pi/3.
(pi*r2)/2 + 4000
pi multipied by the radius sqaured all divided by 2 pi*r^2 ------ 2
