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
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
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

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)
A sphere has a surface area of 18 square centimeters. What is the volume of a sphere?
9 √(2/pi) We start with the formulas for surface area (4 pi r^2) and volume (4/3 pi r^3). If 4 pi r^2 = 18, then r = 3/√(2 pi); plug that into the formula for volume and we get 9 √(2/pi) as the answer.
How do you find the circumference of a circle as a function of its area?
Take the formulas for the area and circumference of a circle, and massage them.R = radius = 1/2 of the diameterA = Area of a circle = pi R2 = pi (D/2)2 = pi D2/4C = Circumference of a circle = (pi D) or (2 pi R)C = 2 pi R = 2 (pi R2)/R(R) C = 2 A(C/2pi) C = 2 AC2 / 2pi = 2 AC2 = 4 pi AC = sqrt ( 4 pi A ) or 2 sqrt ( pi A )
How do you work out the circumfernce of a circle?
you can use 2 formulas... 2 x pi x radius or pi x diameter - dont forget that pi is always 3.14 unlsess said otherwise. :) hope this has helped.......
What are the two formulas pertaining to circles that pi is used in?
Angular measure of a circle: 2*pi radians. Circumference of a circle with diameter d units: d*pi units
How do you find ratio of area to circumference using pi?
Area = pi R2Circumference = 2 pi RArea/Circumference = pi R2/2pi R = 1/2 R
