Pi is the ratio of the diameter to the circumference
circumference/diameter=pi
that's why c=pid or c=2pir

3wx^2 it is the same as 5-2
Let y = ax²+bx+c then substitute all of orders. we'll be doing equations system.

Ok we are at this.
Substitute c = 3 into equation 1 and equation 3.


then addition and subtract for a-b = 3 and a+b = -1

Therefore a = -2, substitute a = -2 in a-b+c=0 or a+b+c=2 but i'm doing a-b+c=0 one.

Therefore b = 1, substitute both a, b and c into y=ax²+bx+c as we get,
