22 divided by 7 = 3.14285714... However, it has been shown that this number is actually larger than pi which equals 3.14159265... A more accurate approximation would be 355 divided by 113. -- Note that are no two rational numbers which can be divided to give the exact value of Pi. A possible method of calculating Pi would use the Madhava-Leibniz series: Pi = (4/1) - (4/3) + (4/5) - (4/7) + (4/9) ... Such a method is capable of calculating Pi to any number of digits (although it becomes quite impractical after a certain point)
Pi divided by thirty two. .0981747704
π/2 = 90 degrees so the complement of π/4 is π/4.
25/pi = 7.957747155
4 times pi times 4 divided by 2 is 78.9568352087

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)
25.7831 (to 4 dp)
As tan(x)=sin(x)/cos(x) and sin(pi/4) = cos(pi/4) (= sqrt(2)/2) then tan(pi/4) = 1
pi is not divided into anything - unless you specify pi/2 or pi/3.6

Volume is 4/3 x "pi" x r3 or 4(pi)r3 divided by 3. Volume=7234.56 when pi is 3.14

Circumference = (4) x (a quarter of a circle) = (pi) x (the diameter)Diameter = (4 x quarter-circle) divided by (pi)Radius = 1/2 the diameter = (2 x quarter-circle) divided by (pi)
