The value of pi is the circumference of a circle divided by its diameter
The circumference of a circle: 2*pi*radius or pi*diameter
PI represents the platinum with Iridium setting of the jewelry. It is mostly used in fine jewelry. The ring might be a fine jewelry.
a pi sign to die fine "Here comes the 'Why?' line!" a shy mind
Volume of a Sphere. Volume= (4/3)(pi)r^3 Multiple 4/3 times pi times the radius to the third power. The surface area of a Sphere is 4(pi)r^2
For a GCSE test or something like that 3.14 would be fine.
to fine the circumference of a circle you take the radius of a circle and multiply it by pi which is 3.14 even thoush there is a like a million other nunbers in pi you only multiply it by 3.14
As long you remember the formula you should be fine....Circumference = 2 * pi * rOr pi * dwhere r = radius & d = diameter of the circle.Also pi (=3.143) can be roughly put down as 22/7 if you more comfy with fractions than the decimals.the equation is 2*pi*rr being the radiusCircumference = pi x diameterCircumference = 2 x pi x radiusPi times D = CD= DiameterC=Circumference
Area of a circle = (pi) x (radius)2 (pi) = about 3.1416 or about 22/7 . (It can never be written down exactly.) (radius)2 = (radius) x (radius)
Remember this and you'll be fine Three point one four one five nine
(pi)(1/pi)=1.4396 ...
It is 2*pi*r*h square units.
the same as pi squared, which is 9.86960440109
