It is pi/4 radians.
A = C^2/(4 pi) The area of the circle is... The circumference squared... divided by 4... divided by pi If you already know the area, then you can multiply it by 4*pi, and then the square root of the product is equal to the circumference! C = (A*(4 pi))^(1/2)
A rhombus can be split into 2 isosceles triangles or divided into 4 right angle triangles
There are 2pi in a circle. If we divide a circle into 8 equal parts, then each part will be pi/4, [(2pi)/8].
As tan(x)=sin(x)/cos(x) and sin(pi/4) = cos(pi/4) (= sqrt(2)/2) then tan(pi/4) = 1

4 times pi times 4 divided by 2 is 78.9568352087
45 degrees or 0.785398163. The first part is pi radians divided by 4, not quite the same thing.
at a 45 degree angle, or pi/4
1/4 pi to find the degree in terms of pi, divide the degree by 180 in this example, 45 / 180 = 1/4
