Two common math formulas that include pi are the area of a circle, given by ( A = \pi r^2 ), where ( r ) is the radius, and the circumference of a circle, which is ( C = 2\pi r ). Both formulas highlight the relationship between a circle's dimensions and the constant pi, approximately equal to 3.14159.

What are 3 formulas that use pi?
Three common formulas that use pi (π) are: The circumference of a circle, given by the formula ( C = 2\pi r ), where ( r ) is the radius. The area of a circle, calculated using ( A = \pi r^2 ). The volume of a cylinder, which is found using ( V = \pi r^2 h ), where ( h ) is the height of the cylinder.
What are the formulas for circumference and area of circles?
The circumference ( C ) of a circle is calculated using the formula ( C = 2\pi r ), where ( r ) is the radius of the circle. The area ( A ) of a circle is given by the formula ( A = \pi r^2 ). In both formulas, ( \pi ) (pi) is a constant approximately equal to 3.14159.
When can you use math formulas for cylinders?
You can use them when finding surface area or volume You can use a formula for a cylinder when finding the area of a cylinder. This is that formula: Areas of top and bottom circles + Area of the side 2(pi x radius2) + 2 x pi x radius x 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.
