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.
What 2 formulas for the circumference of a circle?
The circumference of a circle can be calculated using two primary formulas: ( C = 2\pi r ), where ( r ) is the radius of the circle, and ( C = \pi d ), where ( d ) is the diameter of the circle. Both formulas utilize the mathematical constant ( \pi ) (approximately 3.14159), which represents the ratio of the circumference to the diameter of any circle.
What are 2 math formulas which include pi?

3 mathematical formulas including pi?
Area of a circle: pi*radius^2 Circumference of a circle: 2*pi*radius or diameter*pi Surface area of a sphere: 4*pi*radius^2
What information do you need in order to find the area or circumference of a circle?
To find the area of a circle, you need the radius or diameter; the area can be calculated using the formula ( A = \pi r^2 ) (where ( r ) is the radius) or ( A = \frac{\pi d^2}{4} ) (where ( d ) is the diameter). To find the circumference, you also need the radius or diameter, using the formulas ( C = 2\pi r ) or ( C = \pi d ).

How can you express area and circumference of a circle in terms of pie?
The area ( A ) of a circle can be expressed in terms of pi (( \pi )) using the formula ( A = \pi r^2 ), where ( r ) is the radius of the circle. The circumference ( C ) of a circle is given by the formula ( C = 2\pi r ). Both formulas highlight the fundamental role of ( \pi ) in relating the dimensions of a circle to its geometric properties.
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.
