What are the formulas that include the changes of degree to radian?
To convert from degrees to radians, multiply the number of degrees by (pi / 180). Pi is approximately 3.1416.
What are some formulas that include pi?
Area of a circle = pi*r2 Circumference of a circle = 2*pi*r or pi*d Volume of a sphere = 4/3*pi*r3 Surface area of a sphere = 4*pi*r2 Volume of a cone = 1/3*pi*r2*height Volume of a cylinder = pi*r2*height

Is there any geometrical proof for formulas C2Pir APir2 Ps i am not asking for deriving those formulas i am asking for geometric proofs for results calculated by those formulas.?
If you mean the following:- Circumference of circle: 2*pi*radius Area of circle: pi*radius^2 The above formulas are only approximates because the exact value of pi has never been finally determined because pi is an irrational number.
