Formulas with include pi?
Area of a circle: pi*radius^2 Circumference of a circle: 2*pi*radius or diameter*pi Volume of a sphere: 4/3*pi*radius^3 Surface area of a sphere: 4*pi*radius^2
Why are there two formulas to calculate the circumference of a circle?
They are: 2*pi*radius or as diameter*pi
What are the two formulas for circumference?
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
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 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

What does half pi mean in math?
half pi is 1/2 x 3.14 = 1.57
The 2 formulas that can be used to find the circumference of a circle?
C = 2*pi*rC = pi * dwhere d = diameter and r = radiusSince d = 2r by definition, the formulas are equivilent
What are some math formulas in everyday life?
The area of a rectangle with sides of lengths x and y units is x*yThe area of a circle with radius r is pi*r^2
What is the area if the radius is 32cm?
In math the area of a circle is defined as pi*r^2 which is pi*32^2 or 1024*pi. This is approxometly 3216.99088. Hope that helped :)
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.
What are five formulas that contain pi?
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius2 Volume of a sphere = 4/3*pi*radius3 Surface area of a sphere = 4*pi*radius2 Total surface area of a cylinder = (2*pi*radius2)+(2*pi*radius*height)
